Ultrasound

Tuesday, May 11, 2010

Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Dr. Edward Hill tells us more about ultrasound imaging in todays 60 Second Housecall.

Dr. Hill:

Ultrasound imaging, also called ultrasound scanning or sonography, involves exposing part of the body to high-frequency sound waves to produce pictures of the inside of the body.

Because ultrasound images are captured in real-time, they can show the structure and movement of the bodys internal organs, as well as blood flowing through blood vessels.

Because no radiation is used, ultrasound is the preferred imaging method to diagnose and monitor pregnant women and their unborn infants.

As sound waves pass through the body, echoes are produced that can help identify the size, shape and density of tissues inside the body.

During the procedure, an ultrasound technologist applies a liquid gel to the skin. The gel helps maintain close contact between the skin and transducer and ensures sound waves are freely conducted into and out of the body.

The technologist sweeps the transducer back and forth over the area of interest. The echoes are instantly measured and displayed by a computer.
