What to Expect
Prior to test
The care team will meet with you to talk about:
- Any allergies you may have
- Current medicines, herbs, and supplements that you take and whether you need to stop taking them before the test
- Fasting before the test, such as avoiding food and drink for at least 8 hours before the test
- Whether you need a full bladder before the test
Description of the Test
A gel will be placed over the belly. A hand-held wand is pushed against the skin. The wand sends sound waves into the body. The waves bounce off internal organs and echo back to the wand. The computer changes the echoes into pictures on a screen. The images are examined by the doctor. A photo of them may be taken.
You may be asked to change positions or hold your breath during the exam. You may feel some discomfort if you have a full bladder.
The gel will be cleaned off your belly.
How Long Will It Take?
Will It Hurt?
