摘要目的评估MRI扩散峰度参数对胶质瘤分级的正确性。材料与方法此项前瞻性研究由机构审查委员会批准,所有病人均签署知情同意书。对照17例高级别胶质瘤与11例低级别胶质瘤实性部分的扩散参数--平均扩散度(MD)、节段性各向异性(FA)、平均峰度、径向与轴向峰度(P<0.05为差异有统计学意义
Abstract Objective To evaluate the accuracy of MRI kurtosis parameters in glioma grading. Materials and Methods This prospective study was approved by the institutional review board and all patients signed informed consent. Differences in diffusion parameters (MD, FA, mean kurtosis, radial and axial) between 17 high grade gliomas and 11 low grade gliomas were analyzed. Kurtosis (P <0.05 for the difference was statistically significant
