A CT scan, or computed tomography scan, uses X-rays to take detailed pictures of the inside of the body. It helps doctors find problems like tumors, broken bones, or internal bleeding. During the scan, you lie on a table that moves through a large machine. The procedure usually takes just a few minutes.
Healthcare providers use CT scans to see things that regular X-rays can’t show. For example, body structures overlap on regular X-rays and many things aren’t visible. A CT shows the details of each of your organs for a clearer and more precise view.
CT scans usually take about an hour. Most of that time is for the preparation. The scan itself takes fewer than 10 or 15 minutes. You can resume normal activities after your provider gives you the OK — usually after they complete the scan and make sure the images are of good quality.
