A cardiac computed tomography combines multiple x-ray images to produce a cross sectional image of the heart. The scan is often combined with injection of intravenous contrast dyes to visualize the anatomy of the heart and trace the circulatory path. Some of the common types of heart scans employed are coronary CT angiography, total body CT scan, and calcium score screening scan.
To prepare for a Cardiac CT scan, you must:
- Refrain from caffeine intake
- Avoid any over-the-counter pills
- Inform your doctor if you are pregnant
- Consume only clear liquids
- Wear comfortable, light and loose-fitting clothes
