What It Is
A CT is a noninvasive, painless medical test that helps physicians diagnose and treat medical conditions. CT imaging uses special x-ray equipment to produce multiple images or pictures from the inside of the body and a computer to join them together in cross-sectional views of the area being studied. CT of internal organs, bone, soft tissue, and blood vessels provide greater clarity than conventional x-ray exams. Common uses include cancer detection, biopsy needle insertion, post-traumatic injuries, and aneurysm/stroke analysis.
