CT scans have been used to look at various anatomic regions, but until
recently, have not been useful for the heart because it is continuously
in motion. CT is very effective in looking at "static" areas,
such as the brain, abdominal cavity, and extremities. Most early CT scanners
take 1-8 pictures (slices) per minute, much slower than the rate of the
heart. It’s like the blurry image that occurs when a picture of
a moving object is taken with a still camera.
St. Joseph Heart Institute’s 64-Slice Coronary CT Scanner provides
ultra clear visualizations of the heart and coronary arteries. Our CT
offers different and unique information from angiography. It not only
determines the severity of blockages, but it also directly visualizes
the atherosclerotic plaque deposited in the vessel wall. It can identify
the early stages of soft (fatty and fibrous) plaque formation even before
it can be detected on x-ray angiography images. It also visualizes calcified
plaque, which occurs frequently in chronic coronary artery disease.
An added advantage is that patients who have already undergone revascularization
procedures including stenting and bypass can now be imaged non-invasively.
