What happens during a heart CT scan?
The whole thing takes only a few minutes. You'll change into a hospital gown and lie on a special scanning table. The technologist will clean three small areas of your chest (men may get partially shaved) and place small, sticky electrode patches there. You may get a shot to help your coronary arteries to show up.
During the scan, you’ll feel the table move inside a doughnut-shaped scanner. A computer program analyzes the images to look for calcification.
