The objective of this prospective study was to compare 2-dimensional (2D) and 3-dimensional (3D) images of endometrial pathology in premenopausal and postmenopausal patients. The 3D sonographic images were evaluated with respect to the contour and texture of the endometrium, endometrial to myometrial interface, and visible pathology in the 3D coronal view. Nine female patients referred for routine pelvic ultrasound exams were scanned transvaginally in both 2D and 3D, and common endometrial pathology including polyps, fluid collections, submucosal fibroids, and hyperplasia were identified. Only 44.4% of the pathology identified by 2D was visualized by 3D.
