What is a CT Coronary Angiography?
CT Coronary Angiography (CTCA) is a non-invasive imaging test that uses X-rays and contrast dye to create detailed 3D images of the coronary (heart) arteries.
It helps doctors detect narrowing, blockages, or abnormalities in the blood vessels supplying your heart.
At Curis Life Multispecialty Clinic in Andheri West, our expert radiologists use advanced multi-slice CT scanners to provide high-resolution, accurate images of your heart arteries for early diagnosis and treatment planning.
All CTCA scans are performed only by prior appointment to ensure safety, comfort, and personalised care.
Why is a CT Coronary Angiography(CTCA) Done?
Doctors recommend CTCA to:
- Detect blockages or narrowing (stenosis) in the coronary arteries
- Evaluate chest pain or suspected coronary artery disease (CAD)
- Identify congenital heart vessel anomalies
- Assess coronary artery bypass grafts or stents
- Plan or monitor heart surgeries or angioplasty procedures
- Screen individuals at high risk of heart disease
Symptoms That May Need a CT Coronary Angiography
- Chest pain or tightness (especially on exertion)
- Shortness of breath
- Irregular heartbeats or palpitations
- Dizziness, fainting, or fatigue
- Strong family history of heart disease
- Previous abnormal ECG, stress test, or echocardiogram
Instructions to Follow Before a CTCA
- Fasting: Do not eat or drink anything (except water) for 4–6 hours before the scan
- Hydration: Drink water (if allowed) before and after the scan to protect kidneys
- Avoid caffeine and nicotine for 12 hours before the scan (to keep heart rate low)
- Medication: Continue regular medicines unless advised otherwise (you may be given beta-blockers before the scan to slow heart rate)
- Clothing: Wear loose, metal-free clothes (avoid jewellery, watches, or belts)
- Inform your doctor if you are pregnant, allergic to contrast, or have kidney problems
- Bring previous ECG, stress test, or heart imaging reports for comparison
These instructions will also be provided at the time of booking your appointment.
How the Test is Done
- You will lie on a motorized table that slides through the CT scanner
- Small electrodes will be attached to your chest to monitor your heartbeat
- A contrast dye will be injected into a vein in your arm
- The scanner captures rapid, detailed images of your heart arteries
- The scan is painless and takes about 15–20 minutes
You will be monitored briefly after the scan and then can return to normal activity
