an abdominal ultrasound uses reflected sound waves to produce a picture of the organs and other structures in the upper abdomen. sometimes a special ultrasound is done for a closer look at a specific organ, such as a kidney ultrasound.
an ultrasound does not use x-rays or other types of radiation. during an abdominal ultrasound, a small hand-held unit called a transducer is gently moved over the belly. a computer converts the reflected sound waves into a picture shown on a tv screen.
an abdominal ultrasound may help find problems of the liver, gallbladder, spleen, pancreas, abdominal aorta, and kidneys.
