Computed Tomography

A CT (computed tomography) scan is an X-ray procedure that combines many X-ray images with the aid of a computer to generate cross-sectional views and, if needed, three-dimensional images of the internal organs and structures of the body.

CT scans define normal and abnormal structures in the body. At times, intravenously injected iodine-containing contrast material is used.

Patients with a history of allergy to iodine or X-ray dye should notify their physicians and radiology staff. Oral contrast may also be required for CT abdomen and CT pelvis examinations.

A CT scan is painless and can provide extremely accurate images of body structures in addition to guiding the radiologist in performing certain procedures, such as biopsies of suspected cancers, removal of internal body fluids for various tests, and the draining of abscesses which are deep in the body.

Many of these procedures are minimally invasive and have markedly decreased the need to perform surgery to accomplish the same outcome.
