摘要 目的:观察动态对比增强磁共振(DCE-MRI)在高级别脑胶质瘤与脑转移瘤中的诊断价值。方法:回顾性分析2015年8月—2017年8月我院经手术病理证实为高级别脑胶质瘤(30例)与脑转移瘤(30例)患者影像学资料,所有患者均行DCE-MRI与MRI检查,比较两组检查手段渗透性参数是否存在差异。结果:与脑转移瘤肿实质区相比,高级别脑胶质瘤肿瘤实质区Ktrans(min^(-1))、Ve、Vp值略高,但差异无统计学意义(P>0.05),高级别脑胶质瘤瘤周水肿区Ktrans(min^(-1))、Ve值显著高于脑转移瘤瘤周水肿区,差异有统计学意义(P<0.05),两组瘤周水肿区Vp值相比,差异无统计学意义(P>0.05)。结论:将DCE-MRI用于高级别脑胶质瘤与脑转移瘤的临床诊断中,可通过对瘤周水肿区进行定量分析,有效鉴别两种疾病类型。
