Computed Tomography is a sophisticated form of x-ray imaging that provides pictures of the body in a series of slices. A CT scan shows clear images of bone, internal organs, muscles and blood vessels and allows doctors to distinguish between normal and diseased or injured tissue. The CT scanner resembles a large doughnut, and your body passes quickly through it while the scanner obtains images.

What to expect during your computed tomography exam

Depending on the area of the body being examined, we may ask you to change into a gown. You may be given a contrast dye by mouth or by injection with a small needle. The dye may cause brief nausea or a feeling of warmth.

You’ll lie down on the CT table, which passes quickly through the scanner. You may be asked to hold your breath for short periods of time as sections of your body are scanned.
