Mullerian 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.

The goal of this study is to review MRI defecography, interpretation, and reporting. The multifactorial etiology of pelvic floor dysfunction has led to a variety of treatments with varying degrees of success which are dependent on proper pretreatment diagnosis and characterization. The ability of MRI defecography to identify and characterize isolated or multiple coexistent abnormalities has led to its significantly increased utilization in the diagnosis and successful treatment of pelvic floor dysfunction. Female pelvic floor dysfunction constitutes a spectrum of pathologic conditions afflicting a large proportion of women throughout the world. Knowledge of important landmarks and measurements depicted during MRI defecography is paramount in detecting and determining the severity of these conditions which allows the referring physician to appropriately tailor specific treatment.

The purpose of this article is to discuss the clinical and imaging findings of primary sclerosing cholangitis and its cholestatic mimickers, with a focus on MR cholangiopancreatography (MRCP) utilization and other characteristic MRI imaging findings. Primary sclerosing cholangitis is a rare idiopathic disease of the liver associated with inflammatory bowel disease which results in damage to the bile ducts and liver parenchyma. Although the etiology of primary sclerosing cholangitis is not completely understood, the disorder is thought to be a result of multiple environmental factors. Genetic factors are likewise important given that multiple genes have been linked to primary sclerosing cholangitis. While primary sclerosing cholangitis shares many clinical and imaging characteristics with other cholestatic diseases, the disorder demonstrates unique and distinguishing features. Discriminating between the similarities and differences on MRI with MRCP allows accurate clinical and radiologic diagnosis, facilitating appropriate management with improved patient outcomes.
