A computed tomography (CT) scan, also known as a Computed Axial Tomography scan, is a fast, painless and noninvasive exam that uses special X-ray equipment to produce images of bones, organs, vessels and soft tissue.
During a CT scan, multiple images are taken and compiled into complete, cross-sectional pictures (or slices) of soft tissue, bone and blood vessels. The resulting images reveal details that are typically invisible or difficult to see in a traditional X-ray.
While CT imaging does use a small amount of radiation, the benefits of an accurate diagnosis far outweigh any risk.
