Abdominal Ultrasound
How To Prepare
Tell your doctor if you have had a Reference barium enema Opens New Window or a series of upper GI (gastrointestinal) tests within the past 2 days. Barium that remains in the intestines can interfere with the ultrasound test.
Other preparations depend on the reason for the abdominal ultrasound test you are having.
- For ultrasound of the liver, gallbladder, spleen, and pancreas, you may be asked to eat a fat-free meal on the evening before the test and then to avoid eating for 8 to 12 hours before the test.
- For ultrasound of the kidneys, you may not need any special preparation. You may be asked to drink 4 to 6 glasses of liquid (usually juice or water) about an hour before the test to fill your bladder. You may be asked to avoid eating for 8 to 12 hours before the test to avoid gas buildup in the intestines. Gas could interfere with the evaluation of the kidneys, which lay behind the stomach and intestines.
- For ultrasound of the aorta, you may need to avoid eating for 8 to 12 hours before the test.
