Three-Dimensional Coronal Plane of the Uterus: A Critical View for Diagnostic Accuracy.

Two-dimensional transvaginal and transabdominal ultrasound (US) examinations are the suggested methods for examining the uterus. Three-dimensional (3D) US, which is not compulsory by society guidelines, provides additional uterine views, reassuring users of pathologic conditions not evident on customary sagittal and transverse views. The 3D coronal plane is rarely seen by 2-dimensional US transducers, let alone in extremely retroverted or axial uteri. Ultrasound machines nowadays feature 3D US capability. Our experience is that the coronal uterine view is a problem solver, helping diagnostic abilities of pelvic imaging. We advocate its liberal use and its acquisition in every pelvic scan. In this Pictorial Essay we present examples to demonstrate its use.
