Diagnostic ultrasound in the evaluation of patients with gynecologic cancer.

In the early 1960's, obstetricians realized the usefulness of diagnostic ultrasonography and were largely responsible for much of the early development and advancement of the ultrasonic technique. Recently gray scale ultrasonography has resulted in the ability to conclusively differentiate solid from cystic masses. Research is currently underway regarding tissue identification based on ultrasonic patterns. The combined use of ultrasonic instrumentation and computers may some day enable the ultrasonographer to identify specific tissues within the body. Fine needle aspiration biopsy in combination with cross-sectional ultrasonic scanning in some cases circumvents the need for repeat laparotomy to obtain tissue for histologic diagnosis.
