A method to improve false interpretation of the endometrial echo pattern as homogeneous hyperechogenic.

Endometrial echo patterns are generally evaluated and graded via transvaginal sonography; however, the uterine position can impede adequate visualization, giving the false impression of a hyperechogenic echo pattern before ovulation or oocyte retrieval. Transabdominal sonography can eliminate this error in the majority of cases when transvaginal ultrasound fails to provide diagnostic images of the endometrium.
