CT angiography:A doctor might order a CT angiography, or angiogram, if they want to assess a person’s risk of heart disease. The scan can also help doctors detect damage to the blood vessels, such as aneurysms or blockages. Before the scan, a health professional injects dye into the bl...
or both. For more than 50 years1the coronary angiogram has been used to define epicardial coronary disease. While conventional coronary arteriography provides exceptional spatial resolution and a general road map of the coronary system for catheter-based or surgical intervention to the heart, its cham...
