【摘要】：目的:分析输卵管积液的磁共振成像(MRI)表现,提高MRI诊断的准确性。方法:回顾性研究经手术和病理证实的41例共56个输卵管积液病灶的MRI表现,分析病灶的部位、大小、形态、信号、管壁厚度、增强表现及积液ADC值。结果:56个输卵管积液病灶中单纯性输卵管积液37个,输卵管积脓14个,输卵管积血5个。可见3种MRI形态学类型:Ⅰ型病灶18个(32%),输卵管积液呈管状;Ⅱ型病灶29个(52%),呈囊状合并管状结构;Ⅲ型病灶9个(16%),呈囊状,无管状结构。14个输卵管积脓病灶的平均壁厚0.37cm,注射对比剂后管壁显著强化;其余42个病灶平均壁厚0.17cm,管壁轻度强化。当管壁厚度以0.25cm为界值时,诊断输卵管积脓的敏感度、特异度和准确率分别为72%、95%和83%。单纯积液病灶的平均ADC值为3.0×10-3 mm2/s,明显高于积脓的1.4×10-3 mm2/s及积血的1.9×10-3 mm2/s。术前MRI误诊11个(20%)。结论:MRI能较好的显示输卵管积液的形态特征,绝大多数输卵管积液病灶有典型表现,部分无管状结构的囊性病灶极易误诊。
[Abstract]:Objective: to analyze the MRI findings of fallopian tube effusion and improve the accuracy of MRI diagnosis. Methods: the MRI findings of 56 tubal effusion lesions confirmed by surgery and pathology in 41 cases were retrospectively studied. The location, size, shape, signal, wall thickness, enhancement and ADC value of the lesions were analyzed. Results: of the 56 lesions, 37 were simple tubal effusion, 14 were fallopian tube pus and 5 were fallopian tube hemorrhage. There were 3 types of MRI morphology: 18 lesions of type 鈪，
