Patient Instructions

Talk with your health-care provider about how you should prepare for you specific examination.

What You Can Expect

You may be given some instructions on:

Filling or emptying your bladder: Some ultrasounds, such as transvaginal ultrasound, work best when the bladder is empty. Others may require you to drink water and keep a full bladder.

Eating and drinking: For example, with abdominal exams, you may have to fast for several hours to eliminate gas.

What to wear: Wear comfortable, washable clothing. You may be given a hospital gown and asked to undress from the waist up or waist down.
