What is a CT scan?
A CT (computerised tomography) scan is a quick, pain-free and non-invasive imaging test that uses X-rays and computer technology to create detailed, 3D cross-sectional images of the inside of your body. During the scan, you lie on a table that moves slowly through a ring-shaped scanner, which takes a series of images from many different angles.
Unlike a standard X-ray, which shows a single 2D image, a CT scan combines multiple images to provide a much clearer and more comprehensive view of your bones, organs, blood vessels and soft tissues, such as your muscles, fat and skin. This helps doctors detect even small changes or abnormalities that might otherwise be missed.
CT scans are often used to assess internal injuries, monitor existing conditions or help diagnose unexplained symptoms. Because they capture such precise detail, they play an important role in helping specialists make fast and confident decisions about your care.
