A computed tomography scan (CT scan) uses computers and rotating X-ray machines to create cross-sectional images of the body, taking a series of X-rays from different angles. These images provide more detailed information than normal X-ray images as they create slices or cross-sections of the body. They may also be combined to produce a 3D image of a particular area of the body. They can show the soft tissues, blood vessels and bones in various parts of the body.
Some people might have an allergic reaction to the contrast material.
