Description of the test
Ultrasound technology allows doctors to see inside the body using high-frequency sound waves. These sound waves bounce off of tissues and return to the equipment, which then translates the sound waves into images of the part of the body being monitored.
Ultrasound is a useful tool to diagnose conditions or analyze certain organs. However, sound waves do not go through air or bone. If bone interferes with the image, another test (such a CT scan or an MRI) may be required.
This test takes place in a clinic, hospital, or doctor's office.
