Ultrasound

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 that are analyzed by the scanner to create a visible image.

Understanding Ultrasounds

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 that are analyzed by the scanner 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.

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, which are visible on a “TV screen” and are recorded digitally.

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

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