Computed tomography, more commonly known as a CT scan, is a diagnostic medical test that, like traditional x-rays, produces multiple images or pictures of the inside of the body. CT images of internal organs, bones, soft tissue and blood vessels typically provide greater detail than traditional x-rays, particularly of soft tissues and blood vessels. CT imaging is one of the fastest and most accurate tools for examining the chest, abdomen and pelvis and is often the best method for detecting various cancers, diagnosing spinal problems, injuries, vascular diseases and pulmonary embolisms. The procedure uses X-ray technology to produce a three-dimensional image of a cross-section of your body. Computed tomography (CT) scans are safe, quick and painless. Today’s radiographic technology allows for high-resolution images with extremely low doses of radiation. The amount of radiation used provides much greater benefits than risks.
