摘要 目的探讨磁共振成像(MRI)定量及半定量参数在乳腺肿块性质鉴别中的应用分析。方法选取2021年9月至2023年9月在本院收治的86例乳腺肿块的患者,根据病理学检查结果将其分为良性组50例,恶性组36例,对所有患者都进行常规序列和动态对比增强扫描(DCE-MRI),分别获取其两组患者的DCE-MRI定量参数和半定量参数,比较两组患者的影像学表现,采用ROC曲线分析各指标及二者联合对乳腺肿块良恶性性质鉴别诊断中的效能。结果恶性组的形状不规则、边缘有毛刺征、内部强化不均匀比值均高于良性组,差异有统计学意义(P<0.05);恶性组的K_(ep)、K_(trans)参数较良性组高,Ve参数较良性组降低,差异有统计学意义(P<0.05);良性组和恶性组的半定量参数IAUGC、Max Slope参数较良性组高,差异有统计学意义(P<0.05);ROC分析K_(ep)、K_(trans)、Ve、IAUGC、Max Slope及其联合检测对乳腺肿块良恶性性质鉴别诊断,差异有统计学意义(P<0.05)。结论MRI定量及半定量参数联合使用对乳腺肿块性质鉴别诊断具有重要的价值,它能准确判断良恶性,在临床上具有良好的应用价值。
