Ultrasonography in the diagnosis of gynecologic disorders.

Ultrasonographic examination is being used with progressively greater frequency as an aid in diagnosis of gynecologic disorders but too often without consideration of whether information other than that obtained from clinical examination is needed and whether ultrasonography can supply it. The size, number, and position of pelvic masses and, in some instances, the type of tumor can be identified, but it is not often necessary when operation is clearly indicated. Ultrasonographic screening for diseases of the reproductive organs has been proposed, but its use for this purpose is limited and it is not cost-effective. It should be used as an adjunct to clinical diagnosis, not as a primary diagnostic procedure.
