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.
本研究的目的是比较磁共振成像（MR）（n = 26）、经阴道超声检查（EVS）（n = 14）和子宫输卵管造影（HSG）（n = 20）对26例患者苗勒管异常分类的相对准确性。有24例经手术证实为异常，2例患者子宫正常（1例有阴道纵隔）。MR成像能够诊断出24例中的24例（准确率100%），EVS在12例中诊断正确11例（准确率92%）。HSG仅在4例中诊断正确。在诊断纵隔子宫时，MR成像的敏感性和特异性均为100%，EVS的敏感性为100%，特异性为80%。在区分那些不需要手术的异常情况时，MR成像和EVS的敏感性和特异性均为100%。MR成像和EVS的高准确性允许对子宫异常进行无创鉴别，可使女性免于诊断性腹腔镜检查，促进具有成本效益的诊断。
