CT coronary angiography in Delhi is a non-invasive CT scan of the heart’s arteries that checks for blockages and narrowing — without any catheter being inserted into the body. Often called CTCA or a CT angiogram of the heart, it is a fast, accurate way to look for coronary artery disease in people with chest pain or heart-disease risk. At Edge Imaging & Diagnostics in Delhi, CT coronary angiography is performed on modern CT with careful technique and clear reporting.
This guide explains what CT coronary angiography is, why it is done, how it differs from a conventional angiography, and what to expect.

What Is CT Coronary Angiography?
CT coronary angiography uses a CT scanner and a contrast dye given through a vein to create detailed 3D images of the coronary arteries — the vessels that supply the heart muscle. It shows narrowing, soft or calcified plaque, and blockages, and can also give a calcium score that reflects the burden of hardening in the arteries. Because nothing is passed into the heart, it is a non-invasive alternative to conventional angiography for many patients.
Why Is CT Coronary Angiography Done?
- To investigate chest pain or breathlessness that may be from the heart
- To rule out coronary artery disease in people at low-to-intermediate risk
- When an ECG, TMT or echo result is unclear and more information is needed
- To assess coronary arteries without an invasive procedure
- To check known plaque or after certain heart procedures, as advised by a cardiologist
CT Coronary Angiography vs Other Heart Tests
| Test | What it does |
|---|---|
| CT coronary angiography | Non-invasive CT pictures of the arteries |
| Conventional angiography | Invasive catheter test; can also treat blockages |
| TMT / stress test | Checks the heart under exertion (ECG) |
CTCA is excellent for seeing the arteries and confidently ruling out significant disease; a conventional angiogram is preferred when treatment (like a stent) may be needed at the same time.
How the Scan Is Performed
An IV line is placed for the contrast dye, and you may be given medicine to gently slow and steady your heart rate for sharper images. You lie on the CT table and hold your breath for a few seconds while the scan is taken. The whole visit usually takes about 20–40 minutes, with the scan itself lasting only seconds. You are usually asked to avoid caffeine beforehand and to fast for a few hours; specific instructions are given when you book.
Is CT Coronary Angiography Safe?
Yes, it is generally very safe. It does use X-rays and an iodine-based contrast dye, so tell us about kidney problems, diabetes medicines, asthma, or any previous contrast reaction and whether you could be pregnant. Our team screens for these and takes the right precautions. It is part of our CT scan and cardiac services.
