摘要 目的:探究乳腺病变使用体素内不相干运动扩散加权成像(IVIM–DWI)模型的诊断价值。方法:选取2018年2月至2019年2月南华大学附属第二医院收治的30例乳腺肿瘤患者,均行乳腺多b值扩散加权成像(DWI)扫描,后处理获得体素内不相干运动(IVIM)模型及常规DWI参数。分析良恶性病变各参数的差异,采用受试者工作特征(ROC)曲线分析差异有统计学意义的各参数鉴别诊断效能。结果:恶性病灶的弥散系数(ADC)、灌注不相关扩散系数(D)值均低于良性病灶,差异具有统计学意义(P<0.01),良性病灶的灌注分数(f)值明显低于恶性病灶,差异具有统计学意义(P<0.001),良恶性病灶间的灌注相关扩散系数(D*)值比较,差异无统计学意义(P>0.05);D、ADC、f的曲线下面积分别为0.901、0.689、0.751,D和f的曲线下面积、最大约登指数、灵敏度均高于ADC,差异具有统计学意义(P<0.05)。结论:采用IVIM模型DWI可为诊断乳腺肿块样病变提供更多定量信息,对鉴别病变良恶性具有一定价值。
