Ultrasound
Diagnostic ultrasound is used to examine organs in the chest (usually the heart) and the abdomen (all of the organs). It can diagnose diseases, and it can be used to permit biopsies of various organs and masses. Dr. Norsworthy purchased his first ultrasound machine in 1995, a full decade ahead of most of his colleagues. He and his associates are currently using his eighth machine. Like computers, improvements happen every few years so upgraded equipment is needed.
An ultrasound study of the heart or abdominal organs provides details of the tissues not possible with radiographs.
