n. [肿瘤]星型细胞瘤（astrocytoma 的复数形式）
1.This sagittal section of brain demonstrates a large brainstem glioma. Most gliomas are astrocytomas.
脑干矢状面显示一个较大的脑干胶质瘤。大多数胶质瘤是星形细胞瘤。
2.After all, grade II astrocytomas are much less common than WHO grade IV glioblastomas in middle aged or elderly patients.
其实，中老年人的WHO分类的星形细胞瘤ii级远比星形细胞瘤级IV少见的多。
3.Purpose: to investigate the value of susceptibility-weighted imaging (SWI) in evaluating the histopathologic grade of cerebral astrocytomas.
目的：探讨磁敏感成像(SWI)在脑星形细胞瘤分级中的价值。
4.Results 43/69 astrocytomas were found to be abnormal chromosome clones, including 12/25 astrocytomas, 15/21 anaplastic astrocytoma, and 16/20 glioblastoma respectively.
结果12／25 的星形细胞瘤， 15／21间变型星形细胞瘤和16／20 的多形胶质母细胞瘤存在染色体数量上的变异。
5.Objective To investigate the relationship of VEGF and astrocytomas.
目的探讨血管内皮生长因子VEGF与星形细胞瘤的关系。
6.Materials and Methods MRI Characteristics of the peritumoral edema and brain tumor interfaces of astrocytomas in 84 cases were analyzed and compared with the surgical and pathological results.
材料与方法对84例MRI中星形胶质细胞瘤瘤脑界面、瘤周水肿特点进行分析，并与手术病理对照。
