Computed Tomography (CT)
Computed tomography is commonly referred to as CT scan (formerly referred to as CAT scan). A CT scan is a diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce images of the inside of the body. CT scans are more detailed than standard X-rays and show detailed images of any part of the body, including the bones, muscles, fat, organs and blood vessels.
CT scans may be done with or without contrast. Contrast refers to a substance taken by mouth or injected into an IV line that causes the particular organ or tissue under study to be seen more clearly. Contrast examinations may require you to fast for a certain period of time before the procedure. A laboratory blood draw may also be required before your exam. Your ordering provider's office or the radiology staff will notify you of this prior to the procedure.
You will need to let your provider know if you have ever had a reaction to any contrast media and/or any kidney problems. A reported seafood allergy is not considered to be a contraindication for iodinated contrast. If you have any medical conditions or recent illnesses, inform your doctor.

How to prepare for a CT Scan:
- Wear comfortable, loose-fitting clothing.
- Avoid clothing with metal snaps or zippers.
- Some exams may require you to drink an oral contrast material for a two-hour period prior to your exam.
- Some exams may require IV contrast, if so an RT, RN or paramedic will gain venous access prior to your exam.
- You may be asked to remove your clothing and dress in a hospital gown.
- You will need to remove any metal objects, such as jewelry, from the area of interest.
- Make sure you tell your technologist if you become anxious in confined spaces or are claustrophobic.
