Computed tomography (CT) is a diagnostic imaging test used to create detailed images of internal organs, bones, soft tissue, blood vessels, and many other structures. CT scans generate pictures using a specialized x-ray machine and detector which scans your body from every angle.
CT scanning is often the most effective and efficient method for detecting many different diseases and pathologies. For example, it can be used to identify internal injuries or bleeding in the context of trauma. For a cancer patient, it can allow your radiologist to confirm the presence of a tumor and determine its size and location. Specialized applications such as CT or Virtual Colonoscopy is an alternative to conventional colonoscopy. Innumerable other diagnostic applications exist.
CT is fast, painless, noninvasive and accurate.
