Heart disease remains the leading cause of death worldwide, and early detection is critical to preventing life-threatening events like heart attacks. One of the most advanced tools in modern cardiology is the Coronary CT Angiogram (CCTA)—a non-invasive, highly accurate imaging test that allows doctors to visualise coronary arteries with remarkable detail. If you’ve ever wondered about heart scans, how they work, and whether they’re safe, this blog will answer all your questions.
With rapid technological advancements, CCTA is not just about detecting heart disease; it’s about transforming the way we diagnose, treat, and prevent it. Let's explore its current applications, emerging trends, and why Manipal Hospital Dwarka, Delhi, is your go-to destination for advanced cardiac care.

What is MDCT and How Does It Work?
MDCT (Multidetector Computed Tomography) is the technology that powers Coronary CT Angiograms. This cutting-edge system captures high-resolution images of the coronary arteries in mere seconds. During the CT coronary angiogram procedure, a contrast dye is injected into the bloodstream, making arteries visible on the scan. The result? A detailed 3D image of your heart’s blood vessels helps doctors detect blockages, narrowing, and other abnormalities.
Unlike traditional angiography, which requires a catheter to be inserted into an artery, CCTA is completely non-invasive—no needles, no hospital stays, and no recovery time.
Why is Early Detection of Coronary Artery Disease (CAD) Important?
Coronary Artery Disease (CAD) is the leading cause of heart attacks. It occurs when cholesterol and plaque accumulate in the arteries, restricting blood flow to the heart. Early detection through a Coronary CT Angiogram allows a cardiologist to intervene before a major cardiac event occurs.
Risk Factors for CAD
-
High cholesterol
-
Family history of heart disease
-
Sedentary lifestyle
If you fall into any of these categories, a Coronary CT Angiogram can provide a clear picture of your heart health and help prevent complications.
Applications of Coronary CTA
1. Diagnosis of Coronary Artery Disease (CAD)
A Coronary CT Angiogram is one of the most effective tools for detecting blockages, plaque buildup, and narrowing of the arteries, often before symptoms appear. Early diagnosis means early intervention, which can save lives.
2. Risk Stratification in Cardiac Patients
Doctors use CCTA to assess a patient’s risk of heart disease. If plaque is present but not severe, lifestyle changes and medications can be recommended to prevent disease progression.
3. Evaluation of Coronary Anomalies
Some individuals have congenital abnormalities in their coronary arteries. A CT coronary angiogram helps doctors identify these anomalies, which can be critical for preventing unexpected cardiac complications.
4. Preoperative Planning for Cardiac Procedures
For patients undergoing bypass surgery or stent placement, CCTA provides a clear roadmap of the arteries, helping surgeons plan the procedure with precision.
5. Post-Surgical Monitoring
After stent placement or bypass surgery, CCTA ensures that interventions are working as intended, reducing the risk of complications or restenosis (re-narrowing of arteries).

Risks of a CT Angiogram
While generally safe, CT angiograms carry some risks:
-
Allergic Reactions: Some individuals may experience allergic reactions to the iodine-based contrast dye used during the procedure. These reactions can range from mild nausea to severe.
-
Kidney Function: The contrast dye can affect kidney function, particularly in individuals with pre-existing kidney conditions.
-
Radiation Exposure: CT angiography involves exposure to ionising radiation, which carries a slight risk of cancer over a person's lifetime.
How You Prepare
Proper preparation is crucial for accurate results:
-
Fasting: Avoid eating for at least 4 to 8 hours before the test. Drinking water is usually permitted.
-
Caffeine: Refrain from consuming caffeine for 12 hours prior to the procedure, as it can increase heart rate and affect image clarity.
-
Medications: Inform your healthcare provider about all medications and supplements you're taking. You may be advised to adjust or discontinue certain medications before the test.
-
Contrast Dye Allergies: If you have a known allergy to contrast material, your doctor may prescribe medications (usually steroids) to reduce the risk of an allergic reaction.
-
Clothing and Personal Items: Wear comfortable, loose-fitting clothing. You may need to change into a hospital gown and remove jewellery, glasses, or any metal objects that could interfere with imaging.
What to Expect
Before the Procedure:
-
Medication: You may receive a beta-blocker to slow your heart rate, enhancing image quality.
During the Procedure:
-
Positioning: You'll lie on a motorised table that slides into the CT scanner, which resembles a large doughnut.
-
Contrast Injection: A contrast dye will be injected through an IV in your arm to highlight blood vessels.
-
Breath-Holding: You may be instructed to hold your breath briefly to minimise motion and obtain clear images.
After the Procedure:
-
Observation: You'll be monitored for a short period to ensure there are no immediate reactions to the contrast dye.
-
Resuming Activities: Unless advised otherwise, you can typically resume your normal activities immediately after the scan.
-
Results: A radiologist will analyse the images and send a report to your referring doctor, who will discuss the findings with you.
Future Trends: The Role of AI & Emerging Technologies
The future of Coronary CT Angiography is even more promising with the integration of Artificial Intelligence (AI) and new imaging techniques:
-
AI-Powered Diagnostics: AI is being used to analyse CT scans with precision, identifying blockages and risks faster than ever before.
-
Dual-Energy CT Scans: New CT scanners improve accuracy by differentiating between soft plaques, hardened plaques, and calcium buildup.
-
CT-FFR (Fractional Flow Reserve): This technique goes beyond imaging and helps determine whether a blockage is severe enough to require intervention.
These advancements will make heart disease detection faster, more accurate, and more accessible to patients worldwide.

FAQ's
No, CT coronary angiography is generally not painful. It is a non-invasive imaging procedure where an iodine-based contrast dye is injected through a vein, and CT scans capture images of the coronary arteries. You may feel a warm sensation from the dye or slight discomfort from the IV insertion, but there is no actual pain during the scan.
A CT coronary angiography typically takes 10 to 30 minutes. The scanning process itself is very quick (often under 10 minutes), but preparation—including inserting an IV line, checking vitals, and administering contrast—may take additional time. Patients are usually advised to arrive early for prep and may be observed briefly afterwards.
The cost of a CT coronary angiogram in India typically ranges from ₹7,000 to ₹20,000, depending on the hospital, city, and technology used.
There is no strict age limit for CT angiography. However, it is usually performed on individuals above 30 years of age, especially those at risk for coronary artery disease. Younger patients may be considered if they have symptoms or a strong family history. Kidney function and general health are evaluated before the procedure, especially in older patients.
CT angiography is non-invasive, quicker, and ideal for screening and diagnosing blockages. Traditional (invasive) angiography is more detailed and allows for simultaneous treatment (like stenting). CT angiography is better for low to moderate risk patients and initial evaluation, while invasive angiography remains the gold standard for confirmed cases requiring intervention.
To book a consultation for CT angiography, you can call the Manipal Hospital’s radiology or cardiology department, use their website or mobile app, or visit in person.
