目的:探讨磁敏感成像(SWI)在脑星形细胞瘤分级中的价值.材料和方法:分析18例经病理证实的脑星形细胞瘤,低级别弥漫性星形细胞瘤7例、间变性星形细胞瘤级3例和多形性胶质母细胞瘤级8例的SWI特点.结果:7例低级别弥漫性星形细胞瘤均未见瘤内静脉血管影,肿瘤周围均轻度水肿.3例间变性星形细胞瘤与8例多形性胶质母细胞瘤内均见丰富静脉血管影.1例间变性星形细胞瘤和6例多形性胶质母细胞瘤内均见出血灶,所有间变性星形细胞瘤与多形性胶质母细胞瘤瘤周中至重度水肿.结论:磁敏感成像能提供瘤内出血、瘤周水肿及瘤体血供等特点,对星形细胞瘤分级尤其是高、低级别的判断有重要价值.

Purpose:To investigate the value of susceptibility-weighted imaging(SWI)in evaluating the histopathologic grade of cerebral astrocytomas.Materials and Methods: 18 patients with histologically proven cerebral astrocytomas,including 7 diffuse astrocytomas,3 ana-plastic astrocytomas and 8 glioblastomas before treatment were involved in this study.The features on SWI were analyzed in 18 cerebral astrocytomas.Results: The veins in the tumors were not detected in 7 diffuse astrocytomas.Slight edema round tumors appeared in all the diffuse astrocytomas.Plenty veins in the tumors and severe edema round the tumors appeared in 3 anaplastic astrocytomas and 8 glioblastomas.The hemorrhagic foci were detected in 1 anaplastic astrocytomas and 6 glioblastomas.The edema round the tumors were moderate or severe in all the anaplastic astrocytomas or glioblastomas.Conclusions: Susceptibility-weighted imaging can provide the informations about blood supply,hemorrhagic focus and edema round the tumors.SWI is very useful for preoperative evaluation of the histopathologic grade of cerebral astrocytomas,especially for evaluation of high or low grade astrocytomas.
