MR Imaging of Müllerian Fusion Anomalies.

Müllerian duct anomalies, also called congenital uterine anomalies, are developmental structural disorders of the female genital tract. These anomalies are clinically relevant in patients with a history of infertility and pregnancy-related complications. The American Society for Reproductive Medicine classification system is the most well known, although newer systems, such as from the European Society of Human Reproduction and Embryology/European Society for Gynaecological Endoscopy, are becoming more widely accepted. MR imaging remains the optimal imaging modality due to its superior multiplanar capability and spatial resolution. This review article describes the typical MR appearance of congenital uterine anomalies.
