WHAT IS A CT SCAN?
A CT scan is a painless X-ray that uses a computer to produce detailed cross-sectional images, or “slices,” of parts of the body.
Of all the imaging tests that are currently available, the 3D CT scan is the best at producing images of bone, blood, soft tissues, and blood vessels such as the coronary arteries in the heart, or other arteries in the brain, kidneys, and extremities.
HOW SHOULD I PREPARE?
- You should wear comfortable, loose-fitting clothing for your CT exam.
- Metal objects can affect the image, so avoid clothing with zippers and snaps.
- You may will also be asked to remove hairpins, jewelry, eyeglasses, hearing aids, and any removable dental work, depending on the part of the body that is being scanned.
- You may be asked not to eat or drink anything for one or more hours before the exam.
- Women should always inform their doctor or x-ray technologist if there is any possibility that they are pregnant.
