What is this test?

A pelvic CT scan uses X-rays and a computer to produce cross-sectional images of the pelvis. Reconstruction is an image-processing step that can improve the detail of the scan, and no contrast dye is injected for this test.

Why might I need this test?

This test may be ordered to evaluate pelvic injuries, bone abnormalities, unexplained pain, or the location and extent of a suspicious finding. It can also help assess nearby soft tissues, although the images are primarily focused on the pelvic region.

How is the test performed?

You will lie on a table while a CT scanner rotates around you and takes X-ray images. The scan is usually brief, and a technologist may ask you to remain still or hold your breath during parts of the examination.

How do I prepare for the test?

Follow the instructions provided by the imaging center. You may need to remove items with metal, tell the technologist if you are pregnant or may be pregnant, and arrive with the paperwork or orders for the examination.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may include fractures, destructive or degenerative bone changes, suspicious masses, fluid collections, or other structural abnormalities. The radiologist will interpret the images in the context of your symptoms, examination, and other tests.

Frequently asked questions

Will I receive an injection for this CT scan?
No. “Without contrast” means no contrast dye is injected for this examination, although you may receive a drink if the imaging center instructs you to do so.
Is a CT pelvis scan the same as a pelvic X-ray?
No. CT provides many cross-sectional images and more detailed information than a standard X-ray, particularly for complex fractures and surrounding tissues.
How much radiation will I receive?
CT scans use ionizing radiation, and the amount varies by the body area and examination protocol. The imaging center can explain the expected exposure and any steps used to minimize it.
