The purpose of this study was to compare the relative accuracy of magnetic resonance (MR) imaging (n = 26), endovaginal sonography (EVS) (n = 14), and hysterosalpingography (HSG) (n = 20) in the classification of müllerian duct anomalies in 26 patients. There were 24 cases of surgically proved anomaly, and two patients had normal uteri (one with a vaginal septum). MR imaging allowed diagnosis of 24 of 24 cases (accuracy, 100%), and EVS was correct in 11 of 12 cases (accuracy, 92%). HSG was correct in only four cases. In the diagnosis of septate uterus, MR imaging demonstrated a sensitivity and specificity of 100% and EVS demonstrated a sensitivity of 100% and a specificity of 80%. Both MR imaging and EVS demonstrated a sensitivity and specificity of 100% in distinguishing those anomalies that did not require surgery. The high accuracy of MR imaging and EVS permit noninvasive differentiation of uterine anomalies and can spare women diagnostic laparoscopy, promoting cost-effective diagnosis.
