Diagnostic Test & Treatment
Cardiac CT Coronary Angiogram
A cardiac CT coronary angiogram, also known as multi-slice CT coronary angiography, is a non-invasive imaging procedure that detects problems in the blood vessels supplying the heart muscle. It is chiefly used to diagnose coronary artery disease, the narrowing of the arteries due to fatty or calcium deposits.
01Why It’s Done
Dr Lee may recommend this for patients with:
- Investigating chest pain or suspected coronary artery disease
- Assessing heart-disease risk non-invasively
- Avoiding invasive angiography where possible
02How It Works
- A contrast dye is given through an intravenous drip in the arm.
- Electrodes are placed on the chest to monitor the heart rate.
- A CT scanner captures detailed cross-sectional images of the heart and its arteries.
- The images are analysed by the cardiologist.
03Duration, Recovery & What To Expect
This is a non-invasive scan with a quick recovery. You can usually resume normal activities the same day.
