An arterial Doppler test in Delhi is a painless ultrasound that checks the arteries — most often in the legs — for narrowing, blockages and reduced blood flow. It is the key test for peripheral artery disease (PAD), and it helps find the cause of leg pain on walking, cold or pale feet, and non-healing wounds. At Edge Imaging & Diagnostics in Paschim Vihar, West Delhi, the arterial Doppler is performed on high-resolution colour Doppler ultrasound for accurate, reliable results. This guide explains what an arterial Doppler is, why it is done, who needs it, and what to expect. Reviewed by Dr. Nishant Thapar, MBBS, MD (Radiodiagnosis), Founder — Edge Imaging & Diagnostics, Paschim Vihar, New Delhi. What Is an Arterial Doppler Test? An arterial Doppler is a colour Doppler ultrasound that examines the arteries carrying blood to your limbs. It shows the artery walls, any fatty plaque (atherosclerosis), the degree of narrowing, and the speed and pattern of blood flow. In the legs it maps flow from the groin down to the feet, pinpointing where circulation is reduced — all without a needle, dye or radiation. Why Is an Arterial Doppler Done? To diagnose peripheral artery disease (PAD) and locate narrowings or blockages To find the cause of leg pain or cramps on walking (claudication) that eases with rest To assess cold, pale or painful feet, or weak/absent pulses To evaluate non-healing wounds or ulcers, especially in diabetes To plan or follow up angioplasty or bypass surgery Who Should Get an Arterial Doppler? Your doctor may advise an arterial Doppler if you have leg pain on walking, cold or discoloured feet, slow-healing foot wounds, or risk factors for artery disease such as diabetes, smoking, high blood pressure or high cholesterol. Diabetic patients in particular benefit, as good circulation is essential for healing and preventing serious foot problems. Arterial Doppler checks What it shows Artery wall & plaque Fatty build-up narrowing the artery Degree of narrowing Mild, moderate or severe blockage Blood-flow pattern How much flow reaches the limb Level of blockage Exactly where circulation is reduced How the Arterial Doppler Is Performed You lie comfortably while gel is applied and the radiologist moves the probe along the limb, recording flow at several levels. Blood-pressure cuffs may sometimes be used to compare pressures (for example an ankle-brachial index). The scan usually takes about 30–45 minutes. There is no injection, no radiation and no discomfort, and you can return to normal activity immediately. Is It Safe and How Do I Prepare? The arterial Doppler is completely safe, using only sound waves. Little preparation is needed; wear loose clothing and, where advised, avoid smoking for a few hours before the test as it can temporarily affect blood flow. It is part of our wider ultrasound and colour Doppler services, alongside the venous Doppler and carotid Doppler.

A venous Doppler test in Delhi is a painless ultrasound of the veins — most often the legs — used to detect deep vein thrombosis (DVT), blood clots, varicose veins and poor venous circulation. It shows both the structure of the veins and the flow of blood through them, helping your doctor find the cause of leg swelling, pain or heaviness quickly and safely. At Edge Imaging & Diagnostics in Paschim Vihar, West Delhi, the venous Doppler is performed on high-resolution colour Doppler ultrasound for accurate results. This guide explains what a venous Doppler is, why it is done, who needs it, and what to expect. Reviewed by Dr. Nishant Thapar, MBBS, MD (Radiodiagnosis), Founder — Edge Imaging & Diagnostics, Paschim Vihar, New Delhi. What Is a Venous Doppler Test? A venous Doppler is a colour Doppler ultrasound that examines the veins and the blood flowing through them. In the legs it checks the deep and superficial veins to see whether they are open, whether their valves are working, and — importantly — whether there is a clot (thrombosis) blocking flow. It is the first-choice test for suspected DVT because it is quick, accurate and completely non-invasive. Why Is a Venous Doppler Done? To detect deep vein thrombosis (DVT) — a clot in a deep leg vein that can be dangerous if it travels to the lungs To find the cause of leg swelling, pain, heaviness or redness To assess varicose veins and valve leakage (venous reflux) before treatment To evaluate chronic venous insufficiency or non-healing leg ulcers To check veins in the arm or neck when a clot is suspected there Who Should Get a Venous Doppler? Your doctor may advise a venous Doppler if you have swelling or pain in one leg (especially calf tenderness), visible varicose veins, or risk factors for clots such as recent surgery, long immobility or travel, pregnancy, or a previous DVT. Sudden one-sided leg swelling with pain should be checked promptly, as it can indicate a DVT. Venous Doppler checks What it shows Deep & superficial veins Whether they are open or blocked Blood clot (thrombus) Presence, location and extent of DVT Vein compressibility A key sign used to confirm or rule out clot Valve function (reflux) Leaky valves causing varicose veins How the Venous Doppler Is Performed You lie down (and sometimes stand for varicose-vein assessment). Gel is applied and the radiologist moves the probe along the leg, gently pressing at intervals to check whether the veins compress normally — a clot stops a vein from compressing. The scan usually takes about 20–40 minutes depending on how much is examined. There is no needle, no dye and no radiation, and you can resume normal activity at once. Is It Safe and How Do I Prepare? The venous Doppler is completely safe, using only sound waves. No fasting is needed; wear loose clothing so the legs can be examined easily. It is part of our wider ultrasound and colour Doppler services, alongside the carotid Doppler and other vascular studies.

A venous Doppler of one leg in Delhi generally costs about ₹1,500–₹3,000, and more if both legs or additional studies are needed. Edge Imaging offers transparent pricing — please call us for the current cost. Is the venous Doppler painful? No. It is painless — just a probe and gel, with gentle pressure to check the veins. There is no needle, dye or radiation. How quickly can a DVT be diagnosed? A venous Doppler can confirm or rule out a DVT during the scan itself, and the report is usually available the same day — important because a DVT needs prompt treatment. Do I need any preparation? No fasting or special preparation is required. Wear loose clothing so your legs are easy to examine. Can it check varicose veins too? Yes.

A carotid Doppler test in Delhi is a quick, painless ultrasound of the two large arteries in your neck (the carotid arteries) that carry blood to your brain. It checks whether these arteries are narrowed or blocked by plaque and how well blood is flowing through them — information that helps assess your risk of stroke. At Edge Imaging & Diagnostics in Paschim Vihar, West Delhi, the carotid Doppler is performed on high-resolution colour Doppler ultrasound for accurate, reliable results. This guide explains what a carotid Doppler is, why it is done, who needs it, and what to expect. Reviewed by Dr. Nishant Thapar, MBBS, MD (Radiodiagnosis), Founder — Edge Imaging & Diagnostics, Paschim Vihar, New Delhi. What Is a Carotid Doppler Test? A carotid Doppler is a colour Doppler ultrasound that looks at the carotid arteries on each side of the neck. Ordinary ultrasound shows the wall and structure of the artery, while the Doppler part measures the speed and direction of blood flow. Together they reveal any build-up of fatty plaque (atherosclerosis), the degree of narrowing (stenosis), and whether blood flow to the brain is affected — all without any needle, dye or radiation. Why Is a Carotid Doppler Done? The carotid arteries are a common site for plaque build-up, and a significant narrowing here is an important and treatable cause of stroke. A carotid Doppler helps to: Assess stroke risk by detecting and grading carotid narrowing Find the cause of a TIA (mini-stroke) or stroke Investigate a bruit (an abnormal sound your doctor hears over the neck) Follow up known carotid disease or monitor after carotid surgery/stenting Who Should Get a Carotid Doppler? Your doctor may advise a carotid Doppler if you have had stroke-like symptoms (sudden weakness, slurred speech, facial droop, temporary loss of vision) or if you have risk factors for artery disease, such as: High blood pressure, diabetes, or high cholesterol Smoking or a strong family history of stroke or heart disease Known coronary artery disease or peripheral artery disease A neck bruit found on examination, or planning before major surgery Carotid Doppler checks What it shows Artery wall & plaque Fatty build-up and its type Degree of narrowing Mild, moderate or severe stenosis Blood-flow speed How much flow is reduced Direction of flow Normal or reversed flow How the Carotid Doppler Is Performed The test is simple and comfortable. You lie on your back with your head slightly turned. A little gel is applied to your neck and the radiologist moves the ultrasound probe gently over each side, capturing images and flow measurements. It usually takes about 20–30 minutes. There is no injection, no radiation and no discomfort, and you can go back to normal activity immediately. Is It Safe and Do I Need Any Preparation? The carotid Doppler is completely safe — it uses only sound waves. No fasting or special preparation is needed; you may be asked to avoid a high polo-neck collar so the neck is easy to access. It is part of our wider ultrasound and colour Doppler services, which also include the penile Doppler and other vascular studies.

No. It is completely painless — just a probe and gel moved over your neck, with no needle, dye or radiation. Do I need to fast or prepare? No fasting is needed. Simply wear something with an open neckline so the area is easy to scan. How long does the test take and when do I get results? The scan takes about 20–30 minutes, and the report is usually available the same day. Can a carotid Doppler prevent a stroke? It cannot prevent a stroke by itself, but by detecting significant narrowing early it lets your doctor start treatment — medicines, lifestyle changes, or a procedure — that can substantially reduce your stroke risk.

The quadruple marker test in Delhi — along with the triple marker test — is a second-trimester blood test that screens your baby for Down syndrome, Edwards syndrome and neural tube defects such as spina bifida. Done between 15 and 20 weeks, it is especially useful if you missed the first-trimester screening. At Edge Imaging & Diagnostics in Paschim Vihar, West Delhi, the triple and quadruple marker tests are offered as part of accurate, well-guided pregnancy screening. This guide explains what the triple and quadruple marker tests are, when they are done, the difference between them, and what the results mean. Reviewed by Dr. Nishant Thapar, MBBS, MD (Radiodiagnosis), Founder — Edge Imaging & Diagnostics, Paschim Vihar, New Delhi. What Are the Triple and Quadruple Marker Tests? Both are maternal blood tests done in the second trimester (also called maternal serum screening). They measure substances produced by the baby and placenta, and — adjusted for your age and pregnancy details — estimate the chance of certain conditions. The triple marker test measures three markers (AFP, hCG and estriol). The quadruple (quad) marker test measures a fourth marker as well (inhibin-A), which makes it more accurate. Like all screening tests, they estimate risk rather than give a definite diagnosis. When Is the Test Done? The triple and quadruple marker tests are done between 15 and 20 weeks of pregnancy, ideally around 16–18 weeks. This is later than the first-trimester double marker test and NT scan, which is why the quad test is often the right choice for mothers who came for their first check after the first trimester. What Do They Screen For? Down syndrome (Trisomy 21) Edwards syndrome (Trisomy 18) Neural tube defects such as spina bifida and anencephaly (through the AFP marker) The neural tube (spine) screening is a useful extra that the first-trimester tests do not provide, and it is complemented by the detailed anomaly scan. Triple vs Quadruple Marker — Which Is Better? The quadruple marker test is generally preferred because the extra marker (inhibin-A) improves its detection rate for Down syndrome compared with the triple test, with fewer false alarms. Your doctor will advise which is suitable for you; where available, the quad test is the more accurate second-trimester option. Test Markers measured Timing Triple marker AFP, hCG, estriol 15–20 weeks Quadruple marker AFP, hCG, estriol, inhibin-A 15–20 weeks Understanding Your Results Results are reported as a risk ratio (for example 1 in 1,000) and as screen-positive or screen-negative. A screen-negative (low-risk) result is reassuring. A screen-positive (high-risk) result does not mean your baby has the condition — it means further testing can be offered, such as NIPT, or a diagnostic test like amniocentesis, along with counselling for clear guidance. Is the Test Safe? Completely. It is a simple blood sample from your arm, with no risk to you or your baby. Usually no fasting is needed, and results are available within a few days. Quadruple Marker Test in Delhi — Why Choose Edge Imaging At Edge Imaging & Diagnostics, the triple and quadruple marker tests are offered by Dr. Nishant Thapar‘s team with accurate reporting and, where needed, coordination with your anomaly scan — all under our NABH-aligned quality standards.

The triple or quadruple marker test in Delhi generally costs about ₹1,500–₹3,000. Edge Imaging offers transparent pricing — please call us for the current cost. Do I need to fast for the test? Usually no fasting is required. It is a simple blood test; any instructions will be shared when you book. What is the difference between the triple and quadruple marker test? The quadruple test measures one extra marker (inhibin-A) than the triple test, which makes it more accurate for Down syndrome screening with fewer false positives. I missed my first-trimester screening — can I still be screened? Yes. The quadruple marker test between 15 and 20 weeks is the recommended option if the first-trimester NT scan and double marker window has passed. What does a screen-positive result mean? It means the estimated chance is above the cut-off, not that your baby has the condition. Confirmatory tests such as NIPT or amniocentesis can give a definite answer.

A growth scan in Delhi, often done with colour Doppler, is a third-trimester ultrasound that checks how well your baby is growing and thriving in the final weeks of pregnancy. It estimates your baby’s weight, measures the amniotic fluid, and — with Doppler — assesses the blood flow through the cord and to the baby’s brain. At Edge Imaging & Diagnostics in Paschim Vihar, West Delhi, growth scans with colour Doppler are performed accurately to help keep your baby safe as your due date approaches. This guide explains what a growth scan and colour Doppler are, when they are done, what they check, and who needs them. Reviewed by Dr. Nishant Thapar, MBBS, MD (Radiodiagnosis), Founder — Edge Imaging & Diagnostics, Paschim Vihar, New Delhi. What Is a Growth Scan? A growth scan is an ultrasound that measures your baby’s head, abdomen and thigh bone to calculate an estimated fetal weight (EFW) and plot it on a growth chart. It checks that your baby is growing at a healthy rate — not too small (growth restriction) and not unusually large — and also looks at the amniotic fluid, the placenta and the baby’s position. Unlike the detailed anomaly scan, its focus is growth and wellbeing rather than anatomy. What Is Colour Doppler in Pregnancy? Colour Doppler is a special ultrasound setting that shows blood flow. In a growth scan it is used to check the flow in the umbilical artery (the cord), the baby’s middle cerebral artery (brain), and sometimes the mother’s uterine arteries. These readings tell the doctor whether the placenta is supplying the baby well. Abnormal Doppler flow is an early warning of growth restriction and helps decide whether closer monitoring — or earlier delivery — is needed. When Is a Growth Scan Done? A growth scan is usually done in the third trimester, from about 28–36 weeks, and may be repeated every 2–4 weeks in higher-risk pregnancies. Your doctor decides the timing based on your pregnancy; some mothers need only one, while others need serial scans to track growth and Doppler trends. Growth scan checks What it measures Estimated fetal weight Baby’s size and growth percentile Amniotic fluid (AFI) Whether fluid is normal, low or high Colour Doppler Blood flow in cord and to the brain Placenta & position Placental site and baby’s presentation Who Needs a Growth Scan with Doppler? A growth scan with Doppler is especially advised if you have: High blood pressure or pre-eclampsia Diabetes (pre-existing or gestational) A baby measuring small or large for dates Low or high amniotic fluid A twin or multiple pregnancy Reduced baby movements, or a previous pregnancy with growth problems Why the Growth Scan Matters The growth scan and Doppler together are one of the best ways to spot a baby who is not getting enough nourishment (growth restriction) before it becomes dangerous. Catching this early lets your obstetrician plan extra monitoring and choose the safest time for delivery — which can make a real difference to your baby’s outcome. If a heart concern is suspected, a fetal echocardiography may also be advised. Is the Growth Scan and Doppler Safe? Yes, completely. Both use ultrasound sound waves, not radiation, and are safe for you and your baby, even when repeated. The scan is painless and needs no special preparation. Growth Scan in Delhi — Why Choose Edge Imaging At Edge Imaging & Diagnostics, growth scans and colour Doppler are performed by Dr. Nishant Thapar on modern ultrasound with careful measurement and clear reporting, under our NABH-aligned quality standards.

To book a growth scan in Delhi, call 9555999960 or visit our contact page. Frequently Asked Questions How much does a growth scan with Doppler cost in Delhi? A growth scan with colour Doppler in Delhi generally costs about ₹1,200–₹2,800. Edge Imaging offers transparent pricing — please call us for the current cost. Is colour Doppler safe for my baby? Yes. Doppler ultrasound is used routinely in pregnancy and is safe for you and your baby when done appropriately by an experienced radiologist. How often will I need a growth scan? Many mothers need just one in the third trimester. In higher-risk pregnancies, scans may be repeated every 2–4 weeks to track growth and blood flow, as your doctor advises. How accurate is the estimated fetal weight? Ultrasound weight estimates are usually within about 10–15% of the actual birth weight. They are most useful for tracking the trend in growth over time rather than an exact figure. Do I need any preparation for a growth scan? No special preparation is needed. You can eat normally and a full bladder is not required this late in pregnancy. Where can I get a growth scan near me in West Delhi?

A dating scan in Delhi — also called an early pregnancy or viability scan — is usually the very first ultrasound of your pregnancy. Done at around 6–9 weeks, it confirms that the pregnancy is developing in the right place, checks the baby’s heartbeat, and gives you an accurate due date. At Edge Imaging & Diagnostics in Paschim Vihar, West Delhi, the early pregnancy scan is performed gently and accurately, giving you early reassurance at one of the most anxious times of pregnancy. This guide explains what the dating scan is, when it is done, what it checks, and why getting it on time matters for the rest of your pregnancy. Reviewed by Dr. Nishant Thapar, MBBS, MD (Radiodiagnosis), Founder — Edge Imaging & Diagnostics, Paschim Vihar, New Delhi. What Is a Dating / Viability Scan? A dating scan is an early ultrasound that confirms a pregnancy and establishes how many weeks along you are. It is sometimes called a viability scan because it checks that the pregnancy is growing and that there is a heartbeat. By measuring the baby’s crown-rump length (CRL), it gives the most accurate estimate of your due date — more reliable than dates alone, especially if your cycles are irregular. When Is the Dating Scan Done? The dating scan is usually done between 6 and 9 weeks, although it can be done up to around 13 weeks. A heartbeat can normally be seen from about 6–7 weeks. If you have pain, bleeding, or a history of complications, your doctor may advise an earlier scan; if it is very early, a short repeat scan after a week or two sometimes gives a clearer picture. What Does the Dating Scan Check? Location of the pregnancy: confirming it is inside the uterus and ruling out an ectopic (tubal) pregnancy Heartbeat and viability: confirming the baby’s heart is beating Number of babies: single, twins or more, and the type of twin pregnancy Accurate dating: measuring CRL to set your due date Early wellbeing: the yolk sac, gestational sac and early development Why the Dating Scan Matters for Later Scans An accurate due date is the foundation of good pregnancy care. It ensures that time-sensitive tests are done in their correct window — especially the NT scan (11–13.6 weeks) and later the anomaly scan (18–22 weeks). Getting your dating scan on time keeps the rest of your screening on schedule. How the Scan Is Done and Is It Safe? In early pregnancy a transvaginal scan often gives the clearest view and is completely safe and gentle; later a transabdominal scan over the tummy may be enough. Ultrasound uses sound waves, not radiation, and is safe for you and your baby. The scan is quick and, other than possibly needing a comfortably full bladder for an abdominal scan, needs little preparation.

The double marker test in Delhi is a simple first-trimester blood test that helps screen your baby for the chance of Down syndrome and certain other chromosomal conditions. Done between 11 and 13 weeks — usually together with the NT scan — it measures two pregnancy-related substances in your blood to give an early risk estimate. At Edge Imaging & Diagnostics in Paschim Vihar, West Delhi, the double marker test is offered as part of accurate, well-coordinated first-trimester screening. This guide explains what the double marker test is, when it is done, what the results mean, and how it works with the NT scan. Reviewed by Dr. Nishant Thapar, MBBS, MD (Radiodiagnosis), Founder — Edge Imaging & Diagnostics, Paschim Vihar, New Delhi. What Is the Double Marker Test? The double marker test is a maternal blood test that measures two markers: free beta-hCG and PAPP-A (pregnancy-associated plasma protein-A). The levels of these two substances, adjusted for your age and pregnancy details, help estimate the risk of chromosomal conditions. It is a screening test, meaning it tells you the chance (high or low), not a yes/no diagnosis. When Is the Double Marker Test Done? The double marker test is done in the first trimester, between 11 weeks and 13 weeks 6 days of pregnancy — the same window as the NT scan. Pairing the blood test with the scan on similar dates gives the most accurate combined result. What Does the Double Marker Test Screen For? Down syndrome (Trisomy 21) Edwards syndrome (Trisomy 18) Patau syndrome (Trisomy 13), in many protocols It does not screen for every condition, and it is not the same as a neural tube (spine) screen — that is looked at on the anomaly scan. Double Marker + NT Scan = Combined Screening On its own the blood test is useful, but its accuracy is much higher when combined with the NT scan measurement and your age. Together this is called combined first-trimester screening, and it identifies a large proportion of affected pregnancies while keeping unnecessary invasive tests low. This is why we usually arrange the NT scan and the double marker test around the same time. Understanding Your Double Marker Results Results are usually reported as a risk ratio — for example 1 in 1,500 (low risk) or 1 in 150 (high risk) — along with the marker levels. A “low-risk” or “screen-negative” result is reassuring. A “high-risk” or “screen-positive” result does not mean your baby has the condition; it means further testing can be offered, such as NIPT (a more detailed blood test) or a diagnostic test like CVS or amniocentesis, with counselling to guide you. Screening test Type Best timing Double marker First-trimester blood test 11–13.6 weeks Triple / Quadruple marker Second-trimester blood test 15–20 weeks Is the Double Marker Test Safe? Completely. It is an ordinary blood sample taken from your arm — no risk to you or your baby, and usually no fasting is required. Results are typically available within a few days.

Do I need to fast for the double marker test? Usually no fasting is required. It is a simple blood test; any specific instructions will be given when you book. What does a “high-risk” double marker result mean? It means the estimated chance is higher than the cut-off, not that your baby definitely has a condition. Further tests such as NIPT, CVS or amniocentesis can give a clear answer. How accurate is the double marker test? Combined with the NT scan and your age, first-trimester screening detects a high proportion of Down syndrome pregnancies.

The NT scan in Delhi — the nuchal translucency scan — is an important first-trimester ultrasound done between 11 and 13 weeks of pregnancy. It measures a small fluid space at the back of your baby’s neck to screen, very early, for the chance of Down syndrome and certain other conditions. At Edge Imaging & Diagnostics in Paschim Vihar, West Delhi, the NT scan is performed accurately on high-resolution ultrasound, giving you early reassurance and, when needed, time to plan. This guide explains what the NT scan is, when it is done, what it screens for, and how it works together with the blood tests of first-trimester screening. Reviewed by Dr. Nishant Thapar, MBBS, MD (Radiodiagnosis), Founder — Edge Imaging & Diagnostics, Paschim Vihar, New Delhi. What Is an NT Scan? The NT (nuchal translucency) scan is a specialised ultrasound that measures the thickness of a small, clear fluid collection under the skin at the back of a baby’s neck. All babies have some fluid here; when the amount is increased, it can be associated with a higher chance of chromosomal conditions such as Down syndrome, or with some heart problems. The NT scan is a screening test — it estimates risk; it does not by itself diagnose a condition. When Is the NT Scan Done? The NT scan must be done in a specific window — between 11 weeks and 13 weeks 6 days of pregnancy — when the baby’s crown-rump length is about 45–84 mm. Before or after this window the measurement is not reliable. This is why it is important to have your dating ultrasound on time, so the NT scan can be planned for exactly the right days. What Does the NT Scan Screen For? Combined with your age and blood tests, the NT scan helps estimate the chance of: Down syndrome (Trisomy 21) Edwards syndrome (Trisomy 18) and Patau syndrome (Trisomy 13) Some congenital heart defects and other conditions, when the NT is increased The radiologist also checks early anatomy and, where possible, markers such as the nasal bone, which add to the accuracy of screening. NT Scan + Double Marker: Combined First-Trimester Screening For the best accuracy, the NT scan is usually combined with a double marker blood test (which measures two pregnancy hormones, free beta-hCG and PAPP-A). Together — the scan measurement, the blood results, and your age — these give a single, more reliable risk estimate. This is called combined first-trimester screening, and it detects a large proportion of Down syndrome pregnancies while keeping unnecessary invasive tests to a minimum.

A normal NT measurement with a low-risk screening result is reassuring. An increased NT or a higher-risk result does not mean your baby definitely has a problem — many babies with a raised NT are perfectly healthy. It simply means further testing can be offered, such as NIPT (a blood test), or a diagnostic test like chorionic villus sampling (CVS) or amniocentesis, along with counselling, so you get clear answers. How the NT Scan Is Performed and Is It Safe? The NT scan is a simple, painless ultrasound, usually done over the abdomen (sometimes a transvaginal scan gives a clearer view early on). It uses sound waves, not radiation, and is completely safe for you and your baby. The measurement needs care and a good position of the baby, so it may take a little time — a short wait or gentle movement often helps the baby turn.

Is the NT scan safe? Yes, completely. It is an ordinary ultrasound using sound waves, with no radiation and no risk to you or your baby. Does the NT scan diagnose Down syndrome? No — it is a screening test that estimates the chance. A higher-risk result can be followed by NIPT or a diagnostic test (CVS or amniocentesis) for a definite answer. What if I miss the 11–13 week window? If the window is missed, the NT scan cannot be done reliably. Your doctor may instead advise second-trimester screening such as the quadruple marker test. Does the NT scan tell the baby’s gender? No. Under the PCPNDT Act, the sex of an unborn baby is never disclosed during any scan in India. The NT scan is only for health screening.

The anomaly scan in Delhi — also called a TIFFA scan or Level-2 ultrasound — is one of the most important scans of your pregnancy. Done at around 18–22 weeks, it is a detailed ultrasound that carefully examines your baby’s growth, organs and anatomy from head to toe, checking that everything is developing as expected. At Edge Imaging & Diagnostics in Paschim Vihar, West Delhi, the anomaly scan is performed on high-resolution ultrasound with careful, unhurried attention so you get accurate, reassuring answers about your baby’s health. This guide explains what the anomaly scan is, when it is done, exactly what it checks, and what happens if something needs a closer look. Reviewed by Dr. Nishant Thapar, MBBS, MD (Radiodiagnosis), Founder — Edge Imaging & Diagnostics, Paschim Vihar, New Delhi. What Is an Anomaly Scan (TIFFA / Level-2 Ultrasound)? An anomaly scan is a detailed mid-pregnancy ultrasound. TIFFA stands for Targeted Imaging for Fetal Anomalies, and it is also known as a Level-2 scan or the 20-week scan. Unlike a quick dating or growth scan, the anomaly scan systematically examines each part of the baby — the brain, face, spine, heart, chest, abdomen, kidneys, limbs and more — along with the placenta, umbilical cord and amniotic fluid. Its purpose is to confirm normal development and to detect structural problems early, so that timely advice and planning are possible. When Is the Anomaly Scan Done? The best time for the anomaly scan is between 18 and 22 weeks of pregnancy, ideally around 19–21 weeks. By this stage the baby’s organs are well formed and large enough to see clearly, yet there is still enough amniotic fluid around the baby to give good images. Doing it in this window gives the most information and, if needed, leaves time for any further tests or specialist opinions. Scan in pregnancy Usual timing Main purpose Dating / viability scan 6–9 weeks Confirm pregnancy, heartbeat, due date NT scan 11–13.6 weeks Early screening for chromosomal risk Anomaly scan (TIFFA) 18–22 weeks Detailed check of baby’s anatomy Growth scan + Doppler 28–36 weeks Check growth, fluid and blood flow What Does the Anomaly Scan Check? During a TIFFA scan, the radiologist carefully examines: Brain and skull: shape, structures and fluid spaces Face: lips and palate (to look for cleft lip), eyes and profile Spine: the full length, to check for spina bifida and alignment Heart: the four chambers, major vessels and rhythm Chest and lungs: and the diaphragm Abdomen: stomach, bowel and the abdominal wall Kidneys and bladder: and the urinary system Arms, legs, hands and feet: bones and movement Placenta, cord and amniotic fluid: position, vessels and fluid volume Growth: measurements to confirm the baby is the right size for dates How the Anomaly Scan Is Performed The anomaly scan is a simple, painless ultrasound done on the abdomen (transabdominal). A little gel is applied and the probe is moved gently over your tummy while the radiologist captures detailed images and measurements. Because it is so thorough, it usually takes about 30–45 minutes, and sometimes a little longer if the baby is lying in an awkward position — a short walk or a change of position often helps. No injection, no radiation and no special risk to you or your baby are involved. Is the Anomaly Scan Safe? Yes. Ultrasound uses sound waves, not radiation, and has been used safely in pregnancy for decades. The anomaly scan is completely painless and carries no known risk to the mother or baby. You can eat normally beforehand and resume your day immediately afterwards. What If the Anomaly Scan Finds Something? Most anomaly scans are reassuring and show a normally developing baby. Occasionally the scan finds something that needs a closer look. Depending on the finding, your doctor may advise a repeat or targeted scan, a fetal echocardiography for a detailed heart check, or a diagnostic test such as amniocentesis, along with counselling. Finding an issue early does not always mean a serious problem — but it does allow the right specialists, planning and support to be arranged in good time.

No. Under the PCPNDT Act, revealing the sex of an unborn baby is illegal in India, and it is never disclosed during any scan at our centre. The scan is done purely to check your baby’s health and development. Do I need a full bladder for the anomaly scan? Usually not much preparation is needed at this stage of pregnancy. You can eat normally; any specific instructions (such as a partly full bladder) will be given when you book. Can the anomaly scan detect every problem? The TIFFA scan detects most major structural abnormalities, but no scan can find every possible condition, and some issues develop later. It is a very valuable check, and your doctor interprets it alongside your other tests. Where can I get an anomaly scan near me in West Delhi?
