what is ct scan used for

A CT (computed tomography) scan is a diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce detailed images of the inside of the body. It can be used to visualize nearly all parts of the body, including bones, muscles, organs, and blood vessels, and is particularly well-suited to quickly examine people who may have internal injuries from car accidents or other types of trauma. CT scans are commonly used to diagnose diseases, injuries, and conditions such as cancer, bone fractures, internal bleeding, blood clots, and injuries to the spine and brain. Additionally, CT scans can be used for fluid or tissue biopsies, or as part of preparation for surgery or treatment. They are also used to help locate tumors, investigate internal bleeding, and check for other internal injuries or damage. CT scans are painless, noninvasive, and carry very little risk, and they provide more detailed information than plain X-rays do. Overall, CT scans are a valuable tool for healthcare providers to detect a wide range of health conditions and to plan medical, surgical, or radiation treatment.
