Radiologist fits contrast fluid intravenous drip to a patient's arm prior to a CT scan. Also known as CAT (computed axial tomography) scanning, CT (computed tomography) scanning is a diagnostic technique in which X-rays are passed through the body at different angles to produce cross sectional images. Sometimes a contrast fluid is administered during CT scanning. Contrast media are opaque to X-rays and enhance the contrast of the images, improving the detail of the scans. A computer then produces cross-sectional images of the tissue being examined. This technique provides clearer and more detailed information about body tissues than X- rays used by themselves.
