Computed Tomography (CT) Scan
Computerized tomography (CT scan) or Computer Axial Tomography (CAT) scan is an imaging procedure that uses an X-ray machine connected to a computer. The scan creates cross-sectional images or slices of the internal structures of the body. Sometimes, a contrast material or dye may also be injected into your arm or any other part of your body for a better view of a particular area. The internal structures are easily visible on the CT scan with the help of the dye.
