What is CT Scan?
A Computed Tomography (CT) scan is an imaging method that uses x-rays to create pictures of cross-sections of the body. CT Scans are one of the most important tools in diagnosing and treating medical conditions. They provide detailed images of the inside of the body, and can help doctors to identify problems and plan treatment. CT Scans are usually quick and painless, and can be a vital part of getting the best possible care.

How the Test is Performed
You will lie down on a narrow table that slides into the center of the CT scanner. You are positioned inside the scanner. The x-ray beams rotate around you. Scanning machines that perform the test without stopping are modern and very useful.
A computer creates separate images of the body area, called slices. These images can be stored, viewed on a monitor, or copied to a disk. Three-dimensional models of the body area can be created by stacking the slices together.
You must stay still during the exam because movement causes blurred images. You may be told to hold your breath for short periods. Complete scans most often take only a few minutes. The newest scanners can image your entire body in less than 30 seconds.
Why the Test is Performed
A CT scan creates detailed pictures of the body, including the brain, chest, spine, and abdomen. The test may be used to:
✅ Diagnose an infection
✅ Guide a doctor to the right area during a biopsy
✅ Identify masses and tumors, including cancer
