A computerized tomography (CT) coronary angiogram isan imaging test that looks at the arteries that supply blood to your heart. It might be done to diagnose the cause of chest pain or other symptoms. A CT coronary angiogram uses a powerful X-ray machine to produce images of your heart and ...
What is a CT Coronary Angiogram CT scans have been used to look at various anatomic regions, but have not been useful for the heart because the heart is continuously in motion. CT is very effective in looking at “static” areas, such as the brain, abdominal cavity, and extremities. Most...
"There was no difference incardiac eventsat 90 days or at 18 months between the group that had positive findings on the CT angiogram screening compared to the group that did not have the test," says John W. McEvoy, M.B., BCh., BAO, a Johns Hopkins heart specialist and lead author o...

For more than 50 years 1 the 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 chambers, ...
Heart attack CT angiogram risks Like an angiogram, the X-rays that are involved in a CT angiogram will expose you to radiation. The level of exposure will depend on the machine type that is used. There is some degree of risk related to radiation exposure - such as the potential to harm...
The combination CT scans consisted of a regular, high-tech CT angiogram, or CTA, to map any plaque buildup in the heart's arteries, and a so-calledCT perfusionimaging test, or CTP, to gauge any slowdown in arterial blood flow.
