Importance of Sonographic Endometrial Morphology in Detecting Hyperplasia and Carcinoma

Abstract

In 2008, the American College of Obstetricians and Gynecologists (ACOG) put together a special committee to produce recommendations on the role of transvaginal sonography to evaluate endometrium in postmenopausal women [1]. Transvaginal ultrasonography usually is sufficient for an initial evaluation of postmenopausal bleeding if the ultrasound images reveal a thin endometrial echo (less than or equal to 4 mm), given that an endometrial thickness of 4mm or less has a greater than 99% negative predictive value for endometrial value for endometrial cancer [1].
