The organs in the upper and lower abdomen, like the liver, kidneys, spleen, prostate, bladder, Fallopian tubes and the womb can be examined thoroughly through an ultrasonography. Ultrasonography works with sound waves. During an ultrasonography, the transducer is moved across a certain part of the body. It can also be determined whether there are defects in the aorta within the abdominal cavity. Together with function tests and blood examinations, this examination provides optimal information.
