A CT-scan or computed tomography scan produces cross-sectional images or slices of the parts of body using computer processed X-rays. These slices or images are used for therapeutic and diagnostic purposes.
CT-Scan or X-Ray?
A regular X-ray sends images from a stationary machine through the body to make a “shadow” picture. In CT, the X-ray machine rotates around the body and makes pictures that are like “slices” through the body, providing much more information than a regular X-ray.
A CT-Scan is better than the X-Ray because it can reveal structures of all types of tissue and not just bone.
