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
You will be positioned on a table. A gel will be placed over the belly. A hand-held wand is pushed against the skin. The wand sends sound waves into your body. The waves bounce off internal organs and echo back to the wand. The computer changes the echoes into images on a screen. The images are examined by your doctor. A photograph 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 during the test.
The gel will be cleaned off your belly.
How Long Will It Take?
Will It Hurt?
Most people do not have any problems after this test. You will be able to go back to normal activities.
The images will be sent to a doctor who specializes in reading them. Your doctor will share the results with you.
