摘要
目的探讨MR在卵巢子宫内膜异位囊肿诊断及鉴别诊断中的临床应用价值。方法回顾性研究2019年1月至2020年12月在我院经MR检查诊断为子宫内膜异位囊肿的患者237例,分析比较MR特点与病理结果差异。结果MRI所诊断的237例卵巢子宫内膜异位囊肿患者,179例符合,58例不符合,诊断正确率75%。T_(1)WI及T_(2)WI均呈高信号者123例;T_(1)WI呈高信号,T_(2)WI呈低等信号者54例;T_(1)WI呈低等信号、T_(2)WI呈低等信号者6例;T_(1)WI、T_(2)WI呈混杂信号者52例。DWI呈高及稍高信号、ADC呈低及稍低信号者128例;DWI及ADC呈混杂信号者49例;DWI呈高及稍高信号、ADC呈高信号者31例;DWI呈低信号、ADC呈低及稍低信号者21例;DWI呈低信号、ADC呈高信号者8例。囊内分层及液-液平面者20例,伴“卫星囊”者26例,囊内“阴影征”56例,伴“囊壁缺口征”或“尖角征”者10例。结论MRI能较好地显示卵巢子宫内膜异位囊肿的内部特点及周围粘连情况,掌握其影像特征有助于提高诊断率。
Objective To explore the clinical application value of MR in the diagnosis and differential diagnosis of ovarian endometriosis cysts.Methods A retrospective study of 237 patients diagnosed with endometriotic cysts by MR examination at our hospital from January 2019 to December 2020 was conducted to analyze and compare the differences in MR features and pathological findings.Results Among the patients with ovarian endometriosis cysts diagnosed by MRI,179 cases were consistent,and 58 cases were not,with a correct diagnosis rate of 75%.123 cases showed high signal in both T_(1)WI and T_(2)WI,54 cases showed high signal in T_(1)WI and low signal in T_(2)WI,6 cases showed low signal in T_(1)WI and low signal in T_(2)WI,52 cases showed mixed signal in T_(1)WI and T_(2)WI,128 cases with high and slightly high signals on DWI and low and slightly low signals on ADC;49 cases with mixed signals on DWI and ADC;31 cases with high or slightly high signal on DWI and high signal on ADC;21 cases with low signal on DWI and low or slightly low signal on ADC;and 8 cases with low signal on DWI and high signal on ADC.There were 20 cases with intracapsular delamination and fluid-fluid plane,26 cases with"satellite cyst",56 cases with"shadow sign",and 10 cases with"the wall gap sign"or"sharp angle sign".Conclusion MRI can better show the internal features and surrounding adhesions of ovarian endometriotic cysts,and mastering its imaging features can help improve the diagnosis rate.
