Computed Tomography Scans

Often referred to as a CT scan, computed tomography is an imaging test in which a part of the body is X-rayed from different angles and combined by a computer to produce cross-sectional pictures of internal organs. In some cases, a dye is injected to clarify the image. This test can help diagnose tumors, hemorrhages, head injuries, and bone abnormalities. Barnes-Jewish St. Peters Hospital optimizes protocols to utilize the lowest amount of radiation during this test.

The U.S. Surgeon General, the American College of Obstetricians and Gynecologists and the National Osteoporosis Foundation recommend that all women 65 years and older get a bone density test. Men may develop osteoporosis starting at a later age and progressing more slowly. Your doctor may recommend a bone density scan at a younger age if you have a family history of osteoporosis.

  • Exams typically take 10 minutes or less, but may vary depending on the body part being visualized and the type of exam
  • Weight limit: 440 pounds

Preparing for a computed tomography (CT) scan

Abdominal or pelvic CTs may require a dye to help visualize and highlight. Dyes may be oral or injected. If ordered, drink extra fluids for 48 hours following your scan to help flush the dye from your body.
