A CT (computed tomography) scan, also called a CAT scan, is an imaging technique that combines multiple X-ray images taken from different angles to produce detailed 3D images of bones, organs, blood vessels, and soft tissues inside the body. Unlike a standard X-ray, which provides a flat, two-dimensional image, a CT scan allows doctors to see “slices” of the body.

During a CT scan, you lie on a movable table that slides through a circular opening. Inside, an X-ray tube rotates around your body while detectors on the opposite side measure the X-rays that pass through. A computer then reconstructs these measurements into detailed cross-sectional images . Dense tissues like bone absorb more X-rays, while air-filled spaces absorb less, allowing precise differentiation of structures.

CT scans are widely used to:

• Detect and monitor cancers, tumors, and infections

• Identify bone fractures, internal bleeding, and blood clots

• Guide surgical procedures, biopsies, and radiation therapy

• Evaluate heart, lung, and abdominal conditions

• Track the effectiveness of treatments and detect disease recurrence
