A CT or computed tomography scan, sometimes known as a CAT scan, is a diagnostic tool that, unlike traditional x-rays, provides a more detailed picture of the inside of a patient’s body by scanning it from several angles at once. These images help medical practitioners diagnose a range of conditions. The scans are conducted by qualified radiographers, in the hospital.

1. What does a CT scan show?

CT scans are capable of creating complex and detailed images of a variety of internal body parts, enabling doctors and other medical professionals to get a clear view of a patient’s organs. CT scans can also generate images of the circulatory system’s blood vessels in minute detail, or examine a patient’s bones.
