CTs can be part of your hospital stay or an outpatient appointment. Each type of CT may require specific steps or instructions. We will discuss those details with you before your test.
In general, you can expect to remove all jewelry and items that contain metal. We may ask you to change into a patient gown.
Your scan may require contrast (dye). If so, you’ll get an IV catheter to administer the dye. You may feel a cooling sensation. Contrast doesn’t have side effects, and your body will naturally eliminate it after the test.
The CT scan machine is shaped like a large ring. You will lie on a padded exam table that slowly moves into the machine for the scan. You need to stay very still during this time. During the test, you will hear clicking sounds. The CT technologist may provide instructions, such as asking you to hold your breath briefly. CTs typically take 30 minutes or less.
A radiologist will review your scan images and write a report for your doctor to discuss with you.
