Ted,

An interesting observation. I guess my first response is that for folks younger than I am, prevention would be nice. For the older amongst us, there is the potential radiation risk associated with any CT scan (my concern is much less for myself than for the youngest amongst us). The most common reason to have a CT angiogram is to see if you have narrowed or blocked coronary arteries. But CT angiogram may be done for:

- Aneurysms, irregular bulges or widening of your blood vessels.

- Atherosclerosis (fatty plaques that build inside blood vessels).

- Coronary artery disease.

- Pulmonary embolism.
