Your Radiologist Explains CT (CAT Scan) of the Body
Welcome to Radiology Info dot org!
Hello, I’m Dr. Jay Pahade, a diagnostic radiologist and abdominal imaging specialist at Yale-New Haven Hospital in Connecticut. I’d like to talk with you about computed tomography of the body or body C-T.
Body C-T is a fast, painless and noninvasive exam that uses special x-ray equipment to produce images of internal organs, bones, soft tissue and blood vessels. It’s often used to examine patients with trauma injuries, abdominal pain and is effective for identifying many different types of cancer. Body CT typically refers to a CT exam that may image your chest, abdomen or pelvis either alone or in combination.
If you’re scheduled for a body C-T, there are several things you can do to prepare.
First, talk to your doctor about any recent illnesses and medical conditions. Tell your doctor about all the medications you’re currently taking and whether you have any allergies. If your exam requires intravenous contrast material and you have a known allergy to it, your doctor may prescribe medication to reduce the risk of an allergic reaction. Also, be sure to inform your doctor and the C-T technologist if there is any possibility you might be pregnant.
You may be asked not to eat or drink anything for a few hours before the exam. Wear loose, comfortable clothing and leave any jewelry at home. You may be asked to wear a gown.
You may have some concerns about C-T scanning. While body C-T does expose you to a small dose of radiation, it’s important to consider the value it provides for your care. The benefit of an accurate diagnosis far outweighs any risk.
