PURPOSE: To assess the role of MR imaging in the detection of Asherman's syndrome, especially whenthis is associated with a congenital uterine anomaly. MATERIALS AND METHODS: MR images were obtained in thesemicoronal plane parallel to the long axis of the uterus in 11 patients. Dilatation and curettage involving thein-sertion of an intrauterine device was performed in all patients, and transabdominal metroplasty was performedin four with uterine anomaly. MR imaging findings we r e compared with those of hyste rosalpingograhy in all patients and compared with sur-gical findings in four. RESULTS: The MR findings of uterine synechiademonstrated in nine of 11 patients were focal thickening of the uterine junctional zone (n=2), hypointense fociin the en-dometrium (n=1), or both these findings (n=6). Seven of the 11 patients had associat-ed uterineanomalies, which were demonstrated in all seven by MR imaging. In four of the seven, HSG failed to demonstratethese anomalies. CONCLUSION: MR imaging satisfactorily demonstrated intrauterine lesions in nine of 11 patientswith Asherman's syndrome, and was especially helpful in demonstrating associated uterine anomalies.
