CT Enterography Scan in Delhi: Complete Guide — Crohn’s Disease, Procedure & Cost

CT Enterography scan in Delhi is a specialised CT examination designed to evaluate the small intestine — the longest and most difficult-to-reach segment of the gastrointestinal tract. Unlike standard CT Abdomen, CT Enterography scan in Delhi uses a large volume of neutral oral contrast to distend the bowel loops optimally, combined with IV contrast, to produce detailed images of the small bowel wall, mucosa, and surrounding mesentery. If your doctor has advised a CT Enterography in Delhi, this guide provides a thorough understanding of the procedure, what to expect, and where to get it done.

According to RadiologyInfo.org (American College of Radiology), CT Enterography scan in Delhi and worldwide is the preferred cross-sectional imaging modality for Crohn’s disease assessment and small bowel evaluation. Crohn’s & Colitis Foundation recognises CT Enterography as a key diagnostic tool for IBD characterisation.

What is CT Enterography?

CT Enterography is a specialised form of contrast-enhanced CT scan specifically optimised to evaluate the small intestine (jejunum and ileum). It differs from standard CT Abdomen in two critical ways:

• Oral contrast — The patient drinks a large volume (1,350–1,500 ml) of neutral (water-density) oral contrast material over 45–60 minutes before the scan. This distends the small bowel loops uniformly, allowing clear visualisation of the bowel wall and lumen.
• IV contrast timing — The CT is acquired during the enteric phase (45–55 seconds after IV contrast injection), optimised for evaluating mucosal enhancement and bowel wall changes.

CT Enterography scan in Delhi provides detailed information about bowel wall thickness, mucosal enhancement, mesenteric fat changes, lymph nodes, fistulas, abscesses, and strictures — all critical for managing inflammatory bowel disease and other small bowel conditions.

Quick Answer: CT Enterography scan in Delhi is a specialised CT scan using large-volume oral contrast to distend and evaluate the small intestine. It is the gold standard imaging tool for Crohn’s disease, small bowel tumours, and obscure GI bleeding. The scan takes 60–90 minutes total including oral contrast drinking time.

Why is CT Enterography scan in Delhi Done?

• Crohn’s disease — The primary indication; assesses disease activity, extent, complications (strictures, fistulas, abscesses), and response to treatment
• Small bowel tumours — Gastrointestinal stromal tumours (GIST), carcinoid tumours, adenocarcinoma, lymphoma
• Obscure GI bleeding — When endoscopy is normal but bleeding persists, CT Enterography scan in Delhi identifies the source
• Small bowel obstruction — Identifies the cause, level, and severity of obstruction
• Celiac disease complications — Detecting ulcerative jejunitis, enteropathy-associated T-cell lymphoma
• Radiation enteritis — Post-radiation bowel damage assessment
• Small bowel polyps — In familial polyposis syndromes (Peutz-Jeghers, FAP)
• Mesenteric ischaemia — Evaluating blood supply to the small bowel
• Post-surgical bowel assessment — Following ileostomy, ileal conduit, or bowel resection

Symptoms That Require CT Enterography

• Chronic abdominal pain — especially right lower quadrant pain suggesting Crohn’s disease
• Chronic or recurrent diarrhoea not explained by colonoscopy findings
• Blood in stool (haematochezia) or dark tarry stool (melaena) with negative colonoscopy
• Unexplained anaemia (iron deficiency) with negative upper and lower endoscopy
• Weight loss with malabsorption symptoms
• Abdominal mass with suspected small bowel origin
• Known inflammatory bowel disease (IBD) for disease activity assessment
• Recurrent abdominal pain in patients with known Crohn’s disease
• Suspected small bowel obstruction

Who Should Get CT Enterography?

• Patients with known or suspected Crohn’s disease requiring detailed assessment
• Patients with obscure GI bleeding with negative endoscopic evaluation
• Individuals with unexplained iron deficiency anaemia and negative endoscopies
• Patients with recurrent or chronic abdominal pain requiring small bowel evaluation
• Post-IBD surgery patients for follow-up of anastomotic complications
• Patients with polyposis syndromes requiring small bowel surveillance

Preparation Before CT Enterography

CT Enterography scan in Delhi requires more preparation than standard CT scans due to the oral contrast requirement:

• Fasting — Fast for 4–6 hours before the appointment (no solid food; water and clear liquids permitted)
• Oral contrast drinking — Drink 1,350–1,500 ml of neutral oral contrast (usually Mannitol or Polyethylene Glycol solution) over 45–60 minutes before scanning
• IV contrast preparation — Serum creatinine test required; IV cannula placed at the centre before the scan
• Bowel preparation — Some protocols require prior evening bowel preparation; confirm with your doctor
• Medications — Take regular medications as prescribed; Metformin to be stopped 48 hours prior
• Arrive early — Arrive 90 minutes before scheduled scan time to begin oral contrast drinking

Step-by-Step Procedure for CT Enterography

1. Registration — Present prescription and creatinine report at Edge Imaging, Paschim Vihar
2. Oral contrast drinking begins — Consume 1,350–1,500 ml of neutral contrast over 45–60 minutes
3. IV cannula placement — IV access established while drinking oral contrast
4. Buscopan injection (optional) — Antispasmodic may be given to reduce bowel movement artefacts
5. Positioning — Lie flat on back on the CT table, arms above head
6. Pre-contrast scan — Baseline images acquired without IV contrast
7. IV contrast injection — Iodinated contrast injected via power injector
8. Enteric phase scan — CT acquired at 45–55 seconds optimised for small bowel wall enhancement
9. Portal venous phase — Additional phase for abdominal organ assessment
10. Post-scan observation — 15–30 minutes monitoring after contrast injection
11. Report delivery — Detailed report available within 90 minutes

How Long Does CT Enterography scan in Delhi Take?

CT Enterography scan in Delhi takes considerably longer than routine CT scans due to the oral contrast preparation. Plan for a total visit time of 2–2.5 hours at Edge Imaging & Diagnostics, Paschim Vihar, Delhi — approximately 60–75 minutes for oral contrast drinking, 20–30 minutes for the actual CT scan, and 15–30 minutes post-scan observation. Reports are typically ready within 90 minutes of scan completion.

Is CT Enterography scan in Delhi Safe?

CT Enterography scan in Delhi is a safe, well-tolerated procedure. The neutral oral contrast used is generally well-tolerated, though some patients experience mild bloating or nausea. IV contrast carries a small risk of allergy, which is why kidney function is checked beforehand. Our centre maintains complete emergency equipment and protocols for contrast reactions.

Is CT Enterography scan in Delhi Painful? CT Enterography scan in Delhi is not painful. The oral contrast drinking may cause mild bloating. The IV cannula insertion is a brief pinch. Contrast injection may cause warmth and flushing for 1–2 minutes. The actual scanning is completely painless and non-invasive.

Risks and Complications

• Bloating/nausea from large volume oral contrast — mild and transient
• Contrast allergy — rare; managed with pre-medication in high-risk patients
• Contrast nephropathy — minimised with kidney function pre-testing and hydration
• Radiation exposure — moderate dose; clinically justified for complex GI conditions

Benefits of CT Enterography

• Visualises entire small bowel — The only CT technique offering comprehensive small intestine assessment
• Gold standard for Crohn’s disease — Assesses disease activity, extent, and complications comprehensively
• Identifies bleeding sources — Detects vascular lesions, tumours, and ulcers in the small bowel
• Non-invasive small bowel assessment — Complementary to capsule endoscopy without the risk of capsule retention
• Guides IBD management — Differentiates active inflammation from fibrotic strictures, affecting treatment choice
• Comprehensive abdominal survey — Also evaluates mesentery, lymph nodes, and other abdominal organs

Accuracy of CT Enterography

CT Enterography scan in Delhi has a sensitivity of 83–90% and specificity of 93–98% for detecting active Crohn’s disease. For small bowel tumours, sensitivity exceeds 85%. It performs comparably to capsule endoscopy for Crohn’s disease assessment in the distal small bowel, with the additional advantage of evaluating extraluminal complications (abscesses, fistulas) that capsule endoscopy cannot detect.

Frequently Asked Questions — CT Enterography in Delhi

1. What is the difference between CT Abdomen and CT Enterography?

Standard CT Abdomen uses positive oral contrast and is optimised for parenchymal organs. CT Enterography scan in Delhi uses neutral (water-density) oral contrast in large volume (1,350–1,500 ml) specifically to distend and evaluate the small bowel. The enteric phase timing is also optimised for bowel wall assessment.

2. Can CT Enterography scan in Delhi be done without bowel preparation?

The primary preparation for CT Enterography scan in Delhi is drinking large volume oral contrast — formal bowel preparation (laxatives) is not always required. However, some centres recommend a mild preparation the evening before to reduce residual bowel content. Your gastroenterologist or radiologist will advise the appropriate protocol.

3. Is CT Enterography scan in Delhi the same as CT Colonography?

No. CT Enterography scan in Delhi specifically evaluates the small intestine (jejunum and ileum) using oral contrast. CT Colonography (virtual colonoscopy) evaluates the colon using colonic insufflation with CO₂ or air. They are different examinations for different parts of the GI tract.

4. Is CT Enterography scan in Delhi better than capsule endoscopy?

Both are complementary. Capsule endoscopy provides direct mucosal visualisation but cannot assess extraluminal structures. CT Enterography scan in Delhi evaluates the bowel wall, mesentery, lymph nodes, and complications like abscesses and fistulas that capsule endoscopy misses. Together they provide the most complete small bowel assessment.

5. How much oral contrast do I need to drink?

Approximately 1,350–1,500 ml of neutral oral contrast solution is consumed over 45–60 minutes before the scan. The solution is usually a Mannitol or PEG-based solution diluted in water. It has a mildly sweet taste and is generally well-tolerated.

6. Can CT Enterography scan in Delhi assess Crohn’s disease activity?

Yes. CT Enterography scan in Delhi is the gold standard radiological tool for Crohn’s disease assessment. It distinguishes active inflammatory disease from fibrotic strictures, identifies complications (fistulas, abscesses, phlegmons), and helps guide the choice between medical therapy and surgical intervention.

7. Does CT Enterography scan in Delhi use radiation?

Yes, CT Enterography scan in Delhi uses ionising radiation. The effective dose is approximately 6–15 mSv depending on the protocol. For patients with Crohn’s disease requiring repeated imaging, cumulative radiation must be considered — MR Enterography (MRE) is a radiation-free alternative for young patients.

8. When should MR Enterography be chosen over CT Enterography?

MR Enterography is preferred for young patients with Crohn’s disease requiring frequent follow-up imaging (to avoid cumulative radiation), in pregnancy, and for perianal disease assessment. CT Enterography scan in Delhi is preferred in emergency settings, for patients with MRI contraindications, and when bony or calcification detail is needed.

9. What is the CT Enterography scan in Delhi report useful for?

The CT Enterography scan in Delhi report provides: disease extent and distribution, bowel wall thickness measurements, mucosal enhancement pattern (active inflammation vs fibrosis), identification of complications (strictures, fistulas, abscesses), lymph node assessment, and mesenteric changes. This information directly guides gastroenterologist treatment decisions.

10. How long will I spend at Edge Imaging for CT Enterography?

Plan for 2–2.5 hours at our Paschim Vihar centre: 60–75 minutes for oral contrast drinking, 20–30 minutes for the CT scan, and 15–30 minutes post-scan monitoring. Reports are ready within 90 minutes of scan completion and delivered digitally.

11. Is CT Enterography scan in Delhi covered by insurance?

Most health insurance policies cover CT Enterography scan in Delhi when prescribed by a gastroenterologist for a documented indication such as Crohn’s disease or GI bleeding. Edge Imaging & Diagnostics is empanelled with multiple insurance providers and corporate health programmes.
