【摘要】：目的:分析輸卵管積液的磁共振成像(MRI)表現(xiàn),提高M(jìn)RI診斷的準(zhǔn)確性。方法:回顧性研究經(jīng)手術(shù)和病理證實(shí)的41例共56個(gè)輸卵管積液病灶的MRI表現(xiàn),分析病灶的部位、大小、形態(tài)、信號(hào)、管壁厚度、增強(qiáng)表現(xiàn)及積液ADC值。結(jié)果:56個(gè)輸卵管積液病灶中單純性輸卵管積液37個(gè),輸卵管積膿14個(gè),輸卵管積血5個(gè)�？梢�(jiàn)3種MRI形態(tài)學(xué)類(lèi)型:Ⅰ型病灶18個(gè)(32%),輸卵管積液呈管狀;Ⅱ型病灶29個(gè)(52%),呈囊狀合并管狀結(jié)構(gòu);Ⅲ型病灶9個(gè)(16%),呈囊狀,無(wú)管狀結(jié)構(gòu)。14個(gè)輸卵管積膿病灶的平均壁厚0.37cm,注射對(duì)比劑后管壁顯著強(qiáng)化;其余42個(gè)病灶平均壁厚0.17cm,管壁輕度強(qiáng)化。當(dāng)管壁厚度以0.25cm為界值時(shí),診斷輸卵管積膿的敏感度、特異度和準(zhǔn)確率分別為72%、95%和83%。單純積液病灶的平均ADC值為3.0×10-3 mm2/s,明顯高于積膿的1.4×10-3 mm2/s及積血的1.9×10-3 mm2/s。術(shù)前MRI誤診11個(gè)(20%)。結(jié)論:MRI能較好的顯示輸卵管積液的形態(tài)特征,絕大多數(shù)輸卵管積液病灶有典型表現(xiàn),部分無(wú)管狀結(jié)構(gòu)的囊性病灶極易誤診。
[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，
