CT Scan

What is a CT Scan?

Computerized tomography, often called a CT or CAT scan, is a noninvasive medical test that helps physicians diagnose and treat many medical conditions. CT scans produce cross-sectional images inside the body. These images are studied to determine the appropriate next steps.

CT scans of internal organs, bones, soft tissue and blood vessels provide greater clarity and reveal more details than regular X-ray exams. By using specialized equipment and expertise to create and interpret CT scans of the body, radiologists can diagnose or detect problems such as:

• Blood clots
• Bone fractures
• Colon cancer
• Hand and foot injuries
• Heart disease
• Infections
• Internal injuries and signs of internal bleeding
• Kidney failure
• Liver cancer
• Muscle and bone disorders
• Pancreatic cancer
• Pulmonary embolism
• Spinal problems
• Stroke symptoms

How Should I Prepare?

This procedure is painless. Here is a list of things to do to prepare for your CT scan:

• Make sure you wear comfortable, loose-fitting clothing for your exam.
• Leave metal objects, including jewelry, eyeglasses, dentures and hairpins, at home or remove them before your exam. You may also be asked to remove hearing aids and removable dental work.
• Depending on your procedure, you may be asked not to eat or drink anything for several hours beforehand.
• Inform your physician of any medications you are taking and if you have any allergies.
• If you have a known allergy to contrast material, also called "dye," your doctor may prescribe medications to reduce the risk of an allergic reaction.
• Inform your doctor of any recent illnesses or other medical conditions, and if you have a history of heart disease, asthma, diabetes, kidney disease or thyroid problems.
• Women should always inform their physician and the CT technologist if there is any possibility that they are pregnant.
