A CT Scan is done by a CT machine that uses X-ray techniques to create detailed images of the inside of your body. Your radiologist will ask you to lie on a flat surface that will slowly take you into a tunnel-like structure that rotates to capture X-rays from all angles on the required region of the body. They provide detailed information about the tissues and structures. This scan will last approximately for about 15 minutes. This technique is fast, painless, non-invasive and accurate to reveal internal injuries or disorders.
