A CT scan, also called computerized tomography, is a type of X-ray exam that combines x-rays with powerful computers to create images of the inside of your body in cross section. Often compared to slices in a loaf of bread, the cross-sectional scan images show bones and soft tissue with greater clarity than regular x-rays. If ovarian cancer is suspected, a dye or contrast medium may be used to highlight the spread of cancer.

Before the exam

• Wear comfortable, loose-fitting clothing. You may be given a gown to wear during the procedure.
• You'll be asked to remove your jewelry, hearing aids and eyeglasses. Objects with metal may affect the CT images.
• If a contrast material or dye is used in your exam, you may be asked not to eat or drink anything for several hours beforehand.
• You'll be asked about medications, allergies, recent illnesses and your medical history as some conditions may increase the risk of an unusual adverse effect.
• If you are claustrophobic or staying still for a length of time will cause you pain, talk to your doctor in advance about a mild sedative.

During the exam

Most CT exams are painless, fast and easy. The CT scanner is a box-like machine with a short tunnel in the center and a narrow examination table that slides into and out of this tunnel. The scanners and detectors form a ring that will rotate around you. The technologist will operate the scanner and monitor your examination from a separate windowed room, but you'll be in two-way communication with the technologist the entire time.
