Computerized tomography, commonly known as a CT scan, refers to a medical imaging technique that utilizes X-ray technology. The process utilizes several images of the human body's internal structures that are then reconstructed into a 3D image. CT scans are used to diagnose a wide range of medical conditions, including cancer, blood clots, and internal injuries. Some synonyms for CT scan include CAT scan, computed axial tomography, and computed tomography. These different terms can be used interchangeably to refer to the same imaging technology. Regardless of the name it's known by, CT scans are an important diagnostic tool that help save lives and improve medical outcomes.
