Advantage of transvaginal over transabdominal sonography.

Results with transvaginal sonography (TVS), a new ultrasound diagnostic method, are reported. A total of 40 patients were comparatively examined by transvaginal and transabdominal sonography. In contrast to transabdominal sonography, the transvaginal examination provided additional information in 35% of the patients. The indications and advantages of transvaginal sonography are summarized as compared with the traditional method. The introduction of the method is recommended in all US laboratories where examinations of the pelvis are performed.
