Twenty-five patients with cancer of the uterus underwent transvaginal sonography (TVS) to assess depth of myometrial invasion. All scans were performed with a 5.0-MHz curvilinear array probe (Toshiba, Inc., Tustin, CA) within 1 week of hysterectomy. In 21 cases (84%) sonography correctly predicted the depth of invasion (within 15% of actual). Only one of three cases with cervical involvement was detected. Transvaginal sonography can accurately detect depth of myometrial invasion and is well suited as a screening test to detect high-risk patients for consultation or referral.
