卵巢子宫内膜异位症的MRI诊断(附15例报告)

ENDOMETRIOSIS DIAGNOSED BY MRI

目的：探讨子宫内膜异位症的MRI表现及诊断意义。方法：回顾分析15例经手术病理证实的卵巢子宫内膜异位症的MRI表现，MRI检查用Vectrao．5T超导型成像系统，行横断及矢状面T1、T2加权成像。结果：MRI能很好地显示子宫内膜异位症的陈旧性出血及周围组织粘连这两个病理改变。病灶呈T1加权为高，T2加权为等或高信号影。15例中，MRI共发现17个病灶（手术发现19个），发现率为90％，定性准确率为100％。结论；MRI软组织分辨率高，子宫内膜异位的MRI信号较为特殊，MRI对其定性、定位有很高价值。

Objective:To investigate the feature and diagnostic value of MRI in endometriosis. Metkods:The MRI appearances of 15 cases of endometriosis com firmed by pathology were retrospectively analysed. The patients were examined by superconducted MRI system. T1WI and T2WI were performed onboth axial and sagittal planes. Results:MRI can clearIy show the pathological changes of the stale hemorrhage and peritissue edhesion in endometriosis. The Bignal intensities of endometriosis were hyer-intense on T1WI,iso-intense or hyer-intense on T2WI. The finding rate for endometriosis was 90% ;the accurate rate was 100%. Conclusion: The MRI signal of endometriosis is of characteristic. It is believedthat MRI is the best non-invasive method for the diagnosis and localization of endometriosis.
