[摘 要] 目的：研究动态磁敏感对比增强灌注成像技术(DSC)和扩散加权成像(DWI)在脑胶质瘤中的临床应用价值。方法：63例脑胶质瘤患者行常规MR、常规T1增强扫描，动态磁敏感对比增强灌注及扩散加权成像，分别获得相应扩散系数(ADC)彩图和相对脑血流容量(rCBV)彩图，测量肿瘤实质的灌注参数和弥散参数，进行差异的t检验，对两种诊断方法进行评价并对诊断符合率进行χ2检验。结论：DSC和DWI联合应用为术前无创性地评价胶质瘤的恶性程度、指导定向活检及选择治疗方案等提供重要的帮助。

    [Abstract] Objective Of dynamic susceptibility contrast-enhanced perfusion imaging (DSC) and diffusion-weighted imaging (DWI) in human gliomas in the clinical application value.Methods 63 cases of glioma patients underwent conventional MR, conventional T1-enhanced scan, dynamic susceptibility contrast-enhanced perfusion and diffusion-weighted imaging, respectively, to obtain the corresponding diffusion coefficient (ADC) color pictures and relative cerebral blood flow volume (rCBV) color pictures, measurements substantial tumor perfusion parameters and dispersion parameters, the t-test for differences, the two diagnostic methods for evaluation and diagnosis rate for χ2 test. Conclusion DWI combined DSC and non-invasive preoperative assessment of m alignant glioma, guidance directed biopsy and treatment options to provide significant help. ......
