胶质细胞瘤MRI的临床研究

The Clinical Research of Glioblastoma with MRI Imaging

目的：探讨星形胶质细胞瘤（AG）瘤-脑界面、瘤周水肿MRI像与临床病理之间的关系。方法：对78例AG患者MRI中瘤-脑界面、瘤周水肿的特征进行分析，判断星形胶质细胞瘤的类型和病理分级。结果：78例AG患者中，在加权像上，有11例未发现水肿，瘤周水肿发病率为85.9%；通过瘤周浸润增强分析，发现Ⅰ级与Ⅱ级和Ⅲ-Ⅳ级相比，强化程度和浸润程度有显著性差异（P0.05）。结论：瘤-脑界面MRI强化的形态和程度以及瘤周水肿均与AG细胞瘤的恶性程度有关。

Objective：Explore the the astrocytoma （AG） tumors-brain interface, and the relationship between peritumoral edema in MRI image and clinical pathology.Methods：Analysis of 78 cases AG patients MRI tumor-brain interface characteristics of peritumoral edema,determine the type and pathological grade of glioblastoma.Results：78 cases of AG patients,with weighted images,11 cases found no edema, peritumoral edema incidence rate of 85.9%;peritumoral infiltration enhanced analysis,we can find thatⅠand gradeⅡand gradeⅢ-Ⅳcompared to strengthen the extent and degree of infiltration significant difference （P0.05）.Conclusion：The shape and extent of the tumor-brain interface MRI strengthen and peritumoral edema are related to the degree of malignancy of the AG cell tumor.
