To evaluate the accuracy of preoperative magnetic resonance imaging (MRI) findings relative to surgical presence of deeply infiltrating endometriosis (DIE).
This prospective study included 92 women with clinical suspicion of DIE. The MR images were compared with laparoscopy and pathology findings. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of MRI for diagnosis of DIE were assessed.
DIE was confirmed at histopathology in 77 of the 92 patients (83.7%). Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of MRI to diagnose DIE at each of the specific sites evaluated were as follows: retrocervical space (89.4%, 92.3%, 96.7%, 77.4%, 90.2%); rectosigmoid (86.0%, 92.9%, 93.5%, 84.8%, 89.1%); bladder (23.1%, 100%, 100%, 88.8%, 89.1%); ureters (50.0%, 100%, 95.5%, 95.7%); and vagina (72.7%, 100%, 100%, 96.4%, 96.7%).
MRI demonstrates high accuracy in diagnosing DIE in the retrocervical region, rectosigmoid, bladder, ureters, and vagina.
评估术前磁共振成像（MRI）检查结果相对于深部浸润性子宫内膜异位症（DIE）手术情况的准确性。
这项前瞻性研究纳入了92名临床怀疑患有DIE的女性。将磁共振图像与腹腔镜检查及病理结果进行比较。评估MRI诊断DIE的敏感性、特异性、阳性预测值、阴性预测值及准确性。
92例患者中，77例（83.7%）经组织病理学确诊为DIE。在评估的各个特定部位，MRI诊断DIE的敏感性、特异性、阳性预测值、阴性预测值及准确性如下：宫颈后间隙（89.4%，92.3%，96.7%，77.4%，90.2%）；直肠乙状结肠（86.0%，92.9%，93.5%，84.8%，89.1%）；膀胱（23.1%，100%，100%，88.8%，89.1%）；输尿管（50.0%，100%，95.5%，95.7%）；阴道（72.7%，100%，100%，96.4%，96.7%）。
MRI在诊断宫颈后区域、直肠乙状结肠、膀胱、输尿管及阴道的DIE方面具有较高的准确性。
