The procedure for getting a CAT scan can vary depending on the type of scanner used, but generally involves lying still while a large machine moves around you. You may be asked to hold your breath or stay very still during the scan. A technician will guide the scanner and monitor the images it produces. Depending on the area being scanned, the entire process could take up to an hour.
