Prior to Test

Your doctor may do the following:

• A physical exam
• Blood or urine tests

In some cases your doctor may instruct you to:

• Fast for 8-12 hours before the test. This will decrease the amount of gas in your intestines and make organs easier to see.
• Have a full bladder before the test. You may need to drink 6 or more glasses of water without going to the bathroom.
• Avoid smoking. Smoking can interfere with test results.

Description of the Test

You will lie on a table. Your doctor will put a gel on the skin over the area that will be examined. The gel helps the sound waves travel between the machine and your body.

The ultrasound machine has a hand-held instrument called a transducer. It looks like a microphone or wand. The transducer is pushed against your skin where the gel was applied. The transducer sends sound waves into your body. The waves bounce off your internal organs and echo back to the transducer. The echoes are changed into images that are shown on a screen. The doctor examines the images on the screen. Photographs of the images may be taken.

You may be asked to change positions or hold your breath during the exam.
