Computed Tomography Scan (CAT Scan)
CAT Scans use a thin x-ray beam and very sensitive detectors to get a cross section of the body to be evaluated. Inside the scanner is a rotating structure with an x-ray tube mounted on one side and a series of detectors on the opposite side. Powerful computers then generate actual images of the inside of the body for the radiologist to interpret.
The examination is painless, generally quick and will occasionally require an IV for x-ray dye to get better detail. Please see our article on Contrast Agents for more information.

How to Prepare
A technologist will meet with you prior to your CAT Scan to get additional information and to answer any questions you might have. Please see our CAT Scan form for more information, located under First Visit.
We ask that our female patients tell us if there is any possibility that they are pregnant.
