A CT Scan (Computed Tomography Scan) is an advanced imaging technique used in radiology to create detailed cross-sectional images of the body. It combines X-rays and computer processing to provide clearer and more precise images than standard X-rays. CT scans help diagnose conditions like tumors, fractures, internal bleeding, infections, and organ diseases. The procedure is quick, painless, and may involve contrast dye for better visualization of tissues and blood vessels.
