CT scans, or computed tomography scans, are diagnostic imaging tests that use X-rays to create detailed cross-sectional images of the body. This technology allows medical professionals to see inside the body and identify any abnormalities, such as tumors, fractures, or internal injuries. CT scans are commonly used to diagnose and monitor a variety of medical conditions, including cancer, heart disease, and internal bleeding. The images produced by CT scans provide valuable information to help guide treatment decisions and monitor the progress of a patient's health.
