How you prepare
By Mayo Clinic staffYou'll need to fast for eight to 12 hours before your abdominal ultrasound. Food and liquids in your stomach and urine in your bladder can make it difficult for the ultrasound technician to get a clear picture of your aorta. Ask your doctor if it's OK to drink water during your fast, and if you should continue to take any medications.
