CT stands for Computed Tomography. It is a diagnostic imaging test that uses X-rays and computer technology to create detailed, cross-sectional images of the body.
During a CT scan, the person lies on a table that slides into a doughnut-shaped machine. X-ray beams are sent through the body from different angles, and the computer compiles the data to create detailed, 3D images of the inside of the body.
CT scans are commonly used to diagnose and monitor various conditions, including injuries, infections, tumors, and other abnormalities. They can also be used to guide certain medical procedures, such as biopsies and surgeries.
CT scans involve exposure to ionizing radiation, which can be harmful in high doses. However, the benefits of the test usually outweigh the risks, and the amount of radiation used in a typical CT scan is considered safe.
Interpreting a CT scan requires specialized training and expertise. A radiologist or other healthcare provider who is trained in reading imaging studies typically reviews the CT scan results and makes a diagnosis based on the images.
