An imaging procedure of the internal organs of the abdomen, including the liver, gallbladder, spleen, pancreas and kidneys. The blood vessels to some of these organs can also be evaluated with the use of Doppler techniques. The ultrasound machine sends out high-frequency sound waves, which reflect off body structures to create a picture. There is no ionizing radiation exposure with this test.
