摘要 目的探讨MRI动态增强时间-信号强度曲线(TIC)及弥散加权成像对乳腺良恶性病变的鉴别诊断价值。方法回顾分析52例经病理证实未经治疗的63个乳腺病变磁共振影像学特征,绘制TIC曲线,测量病灶的ADC值,并用ROC曲线分析。结果乳腺良恶性病变的各TIC分型差异均有统计学意义(均P<0.05);良恶性病变的ADC值差异有统计学意义(P<0.05),ROC曲线下面积为0.924;ADC值联合TIC曲线综合诊断与TIC或ADC值单独诊断,其敏感性、特异性及准确率差异均有统计学意义(均P<0.05)。结论 ADC值与TIC曲线的联合应用,可以提高乳腺良恶性病变诊断的准确性,对鉴别乳腺病变具有重要价值。
