An ultrasound is a non-invasive test using sound waves to image organs inside the body. These tests are hamrless even to pregnant women.
Before the Test
There are no special preparations necessary.
During the Test
You will usually lie down for the test on a bed or stretcher. A gel is placed on the skin over the area to be tested. A technologist or physician will lightly rub a hand-held transducer over the area and record the images on a television monitor. There should be no pain. It takes about 30 minutes.
After the Test
A doctor will evaluate the ultrasound images and will then call or send a report of the findings to your own doctor. Your doctor will talk with you about the results of the exam, and help answer any questions you may have.
