A computed tomography (CT) scan) is a medical imaging technique that uses X-rays to create detailed cross-sectional images of the body. It combines multiple X-ray images taken from different angles and processes them using a computer to produce clear, 3D images of internal structures. CT scans are commonly used to diagnose various conditions, including injuries, tumors, and infections. During a CT scan, the patient lies on a table that moves through a large, doughnut-shaped machine. The procedure is quick and painless, typically lasting only a few minutes. Patients may receive a contrast dye to enhance the images, helping doctors better visualize specific areas of concern.
