CTA Abdomen Pelvis With Run-off is a non-invasive study of the abdomen, pelvis and bilateral legs. This CTA is used to detect atherosclerotic disease that has narrowed the arteries of the legs. It will also detect thrombosis (clots) in veins, for example, the large veins in the pelvis and legs. Such clots can travel to the lungs and result in pulmonary embolism.

How to Prepare

  • Drink at least 24 oz of water the day prior to test.
  • Avoid metal on clothing such as snaps or jewelry.
  • Medications are reviewed individually.
  • Allow 30 minutes to an hour for testing.

If you take medicines for diabetes, ask your doctor whether you will need to change how you take them on the day of your CT scan.

Tell your doctor if you:

  • Are pregnant or may be pregnant. Even though cardiac CT uses a low radiation dose, you shouldn’t have the scan if you’re pregnant. The x-rays may harm the developing fetus.
  • Have asthma or kidney problems or are allergic to any medicines, iodine, and/or shellfish. These may increase your chance of having an allergic reaction to the contrast dye.
  • NOTIFY THE CT DEPARMENT OF IODINE ALLERGY.

What To Expect During a CT Test of the Abdomen, Pelvis & Legs

The amount of radiation used is small. This test gives out a radiation dose similar to the amount of radiation you’re naturally exposed to over three years. Contrast dye (iodine) will be used during the CT scan. A small needle connected to an intravenous (IV) line will be put in a vein in your hand or arm. The contrast dye will be injected through the IV during the scan. You may have a warm feeling during the injection. The dye will highlight your blood vessels on the x-ray pictures of the CT scan.

The technologist can see you through a glass window and talk to you through an intercom system.

Moving your body can cause the pictures to blur. You will be asked to lay still and hold your breath for short periods, while each picture is taken. A CT scan usually takes about 15 minutes to complete. After the test, patients can return to their normal activities. Your physician or nurse will call you with results of the scan.
