LAB TEST
Pelvic CT scan
A computed tomography (CT) scan of the pelvis is an imaging method that uses x-rays to create cross-sectional pictures of the area between the hip bones. This part of the body is called the pelvic area. Structures inside and near the pelvis include the bladder, prostate and other male reproductive organs, female reproductive organs, lymph nodes, small intestine, colon, and pelvic bones. Single CT images are called slices. The images are stored on a computer, viewed on a monitor, or printed on film. Three-dimensional models of the body area can be created by stacking the slices together.
How the Test is Performed
You will be asked to lie on a narrow table that slides into the center of the CT scanner. Once you are inside the scanner, the machine's x-ray beam rotates around you. You will not see the rotating x-ray beams. You must be still during the exam, because movement causes blurred images. You may be told to hold your…
How to Prepare for the Test
Certain exams require a special dye. It is called contrast media. It has to be delivered into the body before the test starts. The contrast helps certain areas show up better on the x-rays. Contrast can be given through a vein (IV) in your hand or forearm. Or you may be asked to drink a liquid form of contrast. If…
How the Test will Feel
Some people may have discomfort from lying on the hard table. Contrast given through an IV may cause: Slight burning sensation Metallic taste in the mouth Warm flushing of the body These sensations are normal and most often go away within a few seconds.
Why the Test is Performed
CT rapidly creates detailed pictures of the body, including the pelvis and areas near the pelvis. The test may be used to diagnose or detect: Infection in the pelvis Masses or tumors, including cancer The cause of pelvic pain Injury to the pelvis This test may also help: Guide a surgeon to the right area during a…
Normal Results
Results are considered normal if the organs of the pelvis that are being examined are normal in appearance.
What Abnormal Results Mean
Abnormal results may be due to: Abscess (collection of pus) Bladder stones Broken bone Cancer Diverticulitis
Risks
Risks of CT scans include: Being exposed to radiation Allergic reaction to contrast dye CT scans do expose you to more radiation than regular x-rays. Having many x-rays or CT scans over time may increase your risk of cancer. But the risk from any one scan is small. You and your provider should weigh this risk against…
