Overview
Why It's Done
Risks
- Diagnostic ultrasound is a safe procedure that uses low-power sound waves. There are no known risks. Ultrasound is a valuable tool, but it has limitations. Sound doesn't travel well through air or bone, so ultrasound isn't effective at imaging body parts that have gas in them or are hidden by bone, such as the lungs or head. To view these areas, your doctor may order other imaging tests…
How You Prepare
- Most ultrasound exams require no preparation. However, there are a few exceptions: 1. For some scans, such as a gallbladder ultrasound, your doctor may ask that you not eat or drink for certain period of time before the exam. 2. Others, such as a pelvic ultrasound, may require a full bladder. Your doctor will let you know how much water you need to drink before the exam. Do not urinat…
What You Can Expect
- Before the procedure
Before your ultrasound begins, you may be asked to do the following: 1. Remove any jewelry from the area being examined. 2. Remove some or all of your clothing. 3. Change into a gown. You'll be asked to lie on an examination table. - During the procedure
