Computed tomography, also known as a CT or CAT scan, is a quick, non-invasive diagnostic test that uses x-rays to produce multiple cross-sectional images of the inside of the body and head. The individual images, or “slices”, are recombined to provide a multidimensional view of the body’s interior. CT images show greater detail than traditional x-rays, making them particularly useful in detecting and diagnosing problems in internal organs, soft tissue, and blood vessels. For some CT scans, a contrast material or “dye” may be used to enhance the part of the body being examined; it is typically swallowed by the patient or injected into an IV.
CT is often used in emergency situations to assess the extent of damage to the head and body, and to help find the cause of non traumatic head and body pain.. It is also one of the best procedures for detecting vascular disease, like blood clots and aneurysms, and some forms of cancer, and is often used to aid needle biopsies and tumor treatments. In addition, CT can help identify and treat problems with the spine, the extremities, and other delicate musculoskeletal structures.
