Diagnostic & Screening Tests
Computerized tomography, or CT scan, is a noninvasive imaging test that produces cross-sectional images of the body. Before a CT scan, a contrast material is usually administered to the patient, either orally or intravenously. This material makes the internal organs more visible during the test and can help the provider locate irregularities in the colon and other organs. A CT scan can also help providers to accurately guide the placement of instruments during other screenings or treatments.
During the scan, the patient lies on a table that slides into a donut-shaped machine that scans the body to create images. A computer combines these images to generate cross-sectional views and three-dimensional images of the organ.
