目的
确定磁共振（MR）成像在评估有原发性闭经病史的患者中的准确性。
材料和方法
29 名原发性闭经患者接受了轴向和矢状面的 T2 加权 MR 成像。在选定的病例中进行了对比材料增强和非增强 T1 加权 MR 成像。 23 名患者的 MR 成像结果与手术结果相关，6 名患者的 MR 成像结果与临床结果相关。
结果
17 名女性解剖异常患者（Mayer-Rokitansky-Küster-Hauser 综合征 [n = 9]、阴道横隔 [n = 3]、处女膜闭锁 [n = 1]、宫颈发育不全 [n = 1]）中的 14 名患者获得了手术相关性，证实了 MR 成像结果。在 12 名患有先天性性别分化障碍（睾丸女性化 [n = 5]、真正的雌雄同体 [n = 2]、性腺发育不全 [n = 2]）的 12 名接受手术关联的患者中，有 9 名患者的 16 名性腺中的 13 名（81%）通过 MR 成像正确定位。总体而言，MR 成像患者的分类与手术和实验室检查结果相结合的分类之间存在极好的相关性 (K = 0.88)。
结论
磁共振成像可用于原发性闭经患者的检查，以准确诊断病理状况并制定手术计划。
PURPOSE
To determine the accuracy of magnetic resonance (MR) imaging in the evaluation of patients with a history of primary amenorrhea.
MATERIALS AND METHODS
Twenty-nine patients with primary amenorrhea underwent T2-weighted MR imaging in the axial and sagittal planes. Contrast material-enhanced and unenhanced T1-weighted MR imaging was performed in selected cases. MR imaging findings were correlated with surgical findings in 23 patients and with clinical findings in six patients.
RESULTS
Surgical correlation was available in 14 of 17 patients with female anatomic anomalies (Mayer-Rokitansky-Küster-Hauser syndrome [n = 9], transverse vaginal septum [n = 3], imperforate hymen [n = 1], cervical agenesis [n = 1]), which confirmed MR imaging findings. In nine of 12 patients with congenital disorders of sexual differentiation (testicular feminization [n = 5], true hermaphrodite [n = 2], gonadal dysgenesis [n = 2]) who underwent surgical correlation, 13 of 16 (81%) gonads were correctly localized with MR imaging. Overall, there was excellent correlation between the classification of patients with MR imaging versus classification with the combination of surgical and laboratory findings (K = 0.88).
CONCLUSION
MR imaging is useful in the work-up of patients who present with primary amenorrhea both for accurate diagnosis of pathologic conditions and for surgical planning.
