Ultrasound testing uses sound waves instead of radiation to "see" inside your body. It is a safe, painless procedure.

During this test, high-frequency sound waves are directed at a specific organ. The sound waves hit the target and bounce back as a series of echoes, which the scanner analyzes to create a visible image.

Ultrasounds can be performed to evaluate different parts of the body, including but not limited to the:

• Abdomen
• Aorta
• Bladder
• Gallbladder
• Liver
• Pancreas
• And prostate

In the case of an obstetrical ultrasound (sonogram), sound waves are directed at an embryo or fetus in order to create pictures of a growing baby.

How you prepare for your exam will depend on the type of ultrasound you are scheduled for. To get a list of detailed instructions based on your specific ultrasound. Your doctor will also be able to explain any necessary directions that must be followed.

• Obstetrical Ultrasound (Sonogram)
  Requires a full bladder
• Drink 16 oz of liquid 30 minutes before the exam
• Do not urinate until after the exam
• Children may not accompany you into the exam room. If you must bring children with you, please bring another adult along to stay with them in the waiting area.
• This exam usually takes one hour

At the start of an ultrasound, a water-soluble gel is applied to the area of your body to be examined. An imaging transducer is then moved slowly over the area to produce the images visible on a “TV screen” and recorded digitally.

Most exams take about 30 minutes, although some procedures may be more prolonged.

Following ultrasound testing, the images are read and evaluated by a radiologist, and the results are discussed with your doctor.
