摘要 目的探讨动态磁敏感对比磁共振(DSC-MR)全脑灌注成像在脑肿瘤术前诊断与分级中的应用价值。方法回顾性分析2017年1月至2019年10月于医院进行诊治的70例脑肿瘤患者的临床资料,其中低级别胶质瘤31例,高级别胶质瘤39例,所有患者均接受MR序列扫描,比较低级别胶质瘤与高级别胶质瘤患者的相对局部脑血容量(rrCBV)、相对局部脑血流量(rrCBF),分析rrCBV、rrCBF对不同级别胶质瘤的预测价值。结果高级别胶质瘤患者的rrCBV、rrCBF均高于低级别胶质瘤患者,差异有统计学意义(P<0.05);经ROC曲线分析结果显示,当rrCBV临界值为2.379时,可获得较为理想的灵敏度与特异度,分别为95.24%、92.83%;当rrCBF临界值为1.951时,可获得较为理想的灵敏度与特异度,分别为84.79%、85.78%。结论 DSC-MR全脑灌注成像在脑肿瘤术前诊断与分级中具有较高的应用价值。
