Ultrasound is a diagnostic test that uses high-frequency sound waves to see organs and internal body structures. Unlike radiograph imaging, patients are not exposed to radiation.
During the test, the doctor moves a device called a transducer over the skin covering the body part to be examined, but before it is necessary to put a gel on the skin for the proper transmission of ultrasound. The transducer sends sound waves that bounce off internal tissues that are captured by a computer, which creates images from them that are displayed on a screen.
