A Computed Tomography (CT) scan, also known as Computed Axial Tomography (CAT) scan, is a medical imaging procedure that uses computer-processed combinations of multiple X-ray measurements to produce cross-sectional images of the body. These images provide detailed, three-dimensional views of internal organs, tissues, and structures, helping doctors diagnose and monitor conditions affecting internal organs. The primary functions of CT scans include observing internal tissues and organs, staging cancer, and detecting vascular disease, as well as guiding biopsies, monitoring treatment effectiveness, detecting internal injuries, and examining the digestive tract.
