Computed Tomography

What is a CT scan?
CT scan is a special kind of x-ray that can produce detailed images of the body by taking pictures of the
area being scanned in thin layers. It is used to view soft tissue, bone and blood vessels within the body.

Who should NOT have a CT exam?
If you are pregnant or may be pregnant, consult your physician prior to the exam.

How should I prepare for my CT exam?
- Please bring previous x-rays of the area being examined.
- Depending on the type of CT, you may be required to fast 4-6 hours before the exam.
- Some exams require drinking a liquid contrast agent up to two hours prior to your exam.

What should I wear for my CT exam?
Please wear comfortable clothing. If needed, a dressing gown will be provided.

What should I expect during my CT exam ?
Depending on the type of exam, you may be asked to hold your breath and remain still for a few moments while images are being recorded by the scanner. You may hear the scanner rotating while the exam table moves slowly through scanner. Some CT scans require an injection of a contrast agent that enhances the clarity of the images. Please tell the technologist if you have any allergies to food or medicine or have had an allergic reaction during a previous CT scan or X-Ray.
