  • Allergy to iodine or shellfish
  • Blood disorders

What to Expect

Prior to test

Recent tests will be reviewed before the x-ray. Leading up to the test:

  • A laxative and enema may be given the day before. It will empty your digestive system. Stool in the gut may make it harder to read the x-rays.
  • Food and drink may need to be stopped after midnight the night before.

Description of the Test

An IV will be placed. The contrast material and any needed medicine will be passed through the IV. You will lie on a table for 30 to 60 minutes. X-rays will be taken at regular intervals. This will allow the doctor to see these body parts at work. It will better show where problems might be. You may be asked to hold your breath each time an x-ray is taken. You will also be asked to empty your bladder in a bathroom before the last x-ray.

After Test

You can return to normal activity and diet.

How Long Will It Take?

About 60 to 90 minutes

Will It Hurt?

This test will not hurt. A warmth or heat may be felt as the contrast is given through the IV.

Results

It may take a few days to get test results. The doctor will talk to you about the results and how it may affect treatment.
