FAQs – Patient’s Guide

Why do I need a full bladder for a pelvic ultrasound examination?
Sound waves (used in ultrasound), travel more effectively through liquids than through other body parts or air. If the bladder is full, it facilitates a passage of sound waves and acts as a “window” to see the uterus and ovaries lying behind the bladder better.
Why can't I eat or drink anything before my abdominal ultrasound?
Air is introduced into the stomach when you eat, drink or chew gum. Ultrasound waves don’t penetrate well through air, which makes it more difficult to see target organs. Having food may also cause the gall bladder to contract, making it difficult to examine the gallbladder.
