What to Expect

You will be asked to fill out a short medical history questionnaire. Once completed, you may be asked to remove jewelry and metal objects, such as watches, necklaces, eyeglasses, and the like.

If the your chest, abdomen, or pelvis are being scanned, you may need to change into a hospital gown. If the exam will use IV contrast, an IV line will be placed by the CT technologist once the patient is in the exam room (see general instructions). You will lie on a table that slides into the scanner.

Most CT exams take about five minutes. You will be required to remain still during this time.
