The aim of this study was to determine the accuracy of MR imaging in revealing complex vaginal fistulas.
Fifteen patients with clinical symptoms of vaginal fistulas were examined with MR imaging, using a combination of T1-weighted, T2-weighted, and fast multiplanar inversion recovery sequences in the axial plane, along with T2-weighted and fast multiplanar inversion recovery sequences in the sagittal plane. Observers examined the scans for a fistula and any associated masses or collections. The MR findings were recorded with the observers unaware of the results of cystoscopy and sigmoidoscopy under anesthesia. The MR findings were correlated with examination under anesthesia.
Vaginal fistulas were seen in ten patients. All fistulas were confirmed surgically. Of the five patients with no fistulas revealed on MR imaging, examination under anesthesia also revealed no fistulas in four. However, in the fifth patient, examination under anesthesia revealed an epithelialized track, which was not seen on MR imaging.
MR imaging was accurate in revealing and delineating the extent of vaginal fistulas in patients with clinical symptoms of such fistulas.
本研究的目的是确定磁共振成像（MR成像）在揭示复杂阴道瘘方面的准确性。
对15例有阴道瘘临床症状的患者进行MR成像检查，在轴位平面使用T1加权、T2加权和快速多平面反转恢复序列组合，同时在矢状平面使用T2加权和快速多平面反转恢复序列。观察者检查扫描图像以寻找瘘管以及任何相关的肿块或积液。在观察者不知道麻醉下膀胱镜检查和乙状结肠镜检查结果的情况下记录MR成像结果。将MR成像结果与麻醉下检查结果进行对比。
10例患者发现阴道瘘。所有瘘管均经手术证实。在MR成像未显示瘘管的5例患者中，麻醉下检查也有4例未发现瘘管。然而，在第5例患者中，麻醉下检查发现一条上皮化通道，而MR成像未显示。
MR成像在揭示有此类瘘管临床症状患者的阴道瘘并描绘其范围方面是准确的。
