Computed tomography (CT), sometimes called CAT scan, is a non-invasive, painless medical test that helps physicians diagnose and treat medical conditions. CT imaging uses special x-ray equipment to produce multiple images or pictures of the inside of the body and a computer to join them together in cross-sectional views of the area being studied. CT scans of internal organs, bone, soft tissue and blood vessels provide greater clarity than conventional x-ray exams. Using specialized equipment and expertise to create and interpret CT scans of the body, radiologists can more easily diagnose problems such as cancer, cardiovascular disease, infectious disease, trauma and musculoskeletal disorders.

Advancements in imaging technology now allow CT scanners to obtain multiple slices in a single rotation. These scanners, called “multi-slice CT” or “multi-detector CT,” allow thinner slices to be obtained in a shorter period of time, resulting in more detail, additional view capability and shorter patient exam time. This is beneficial for all patients but especially children, the elderly and critically ill.
