CT Scan Preparation

• Preparation for your CT Scan will depend on the type of exam.
• Notify staff if you are nursing or if there is a chance you could be pregnant.
• Please bring previous imaging study results (x-ray, MRI, CT, etc.) such as reports, films or CD-roms if available.
• Please arrive 15 minutes early to verify your registration.

During your exam – what to expect

• You will lie on a cushioned table, and once comfortably positioned, the tabletop will move through a gantry (shaped like a big donut), which houses the x-ray tube and a set of detectors.
• In some cases, a special “coil,” a device to hold part of your body, is used to ensure proper alignment.
• Multiple, low-dose x-rays are passed through the body at different angles. Images are acquired by detectors that measure the x-rays that pass through your body.
• The computer processes this information to form an image that the radiologist will review and interpret.
• Some CT studies require a contrast material to enhance the visibility of certain tissues or blood vessels. In this instance, you are given an I.V. in your hand or arm. Once the contrast is injected, you may feel a warm, flushed sensation, and experience a metallic taste in your mouth that lasts for about two minutes.
• You will receive special instructions if your exam requires you to consume an oral contrast agent (barium sulphate) in advance.
• Depending on the type of exam, your CT scan can take anywhere from 10-30 minutes.

What happens after the exam?

• A radiologist who specializes in a specific area of the body will review your images (i.e., a body radiologist will review images of your abdomen).
• The radiologist prepares a diagnostic report to share with your doctor.
• Your doctor will consider this information in context of your overall care, and talk with you about the results.
