| 摘 要： | 目的：探讨T2＊加权血管成像（SWAN）序列在评估脑胶质瘤病理分级中的价值。方法：对行SWAN序列扫描的17例病理证实的脑胶质瘤患者图像进行分析，比较不同级别胶质瘤内磁敏感伪影（MsA）hk积的差异。结果：17例患者中低级别胶质瘤7例（WHOI～II级），高级别胶质瘤10例（WH0Ⅲ～Ⅳ级），高级别胶质瘤组在SWAN序列上显示的MSA体积大于低级别胶质瘤组，利用Wilconxon秩和检验，差异有统计学意3Y,（P〈0．05）。结论：应用SWAN序列可为脑胶质瘤术前分级提供重要信息。

| Abstract: | Objective： To estimate the value of T2 star weighted angiography （SWAN） sequence in the pathologic grading of cerebral gliomas. Methods： Imagings of seventeen patients examined by SWAN with confirmed gliomas proved by pathological examinations were analysed. The difference of the volume of magnetic susceptibility artifact （MSA） in different seventeen patients, 7 were low-grade glioma grading （WHO grade glioma was compared. Results： Among all the I - II ）,whhie 10 were high-grade glioma（WHO grade Ⅲ -Ⅳ）.The volume of MSA in the high-grade glioma was significantly larger than that in the lowgrade glioma, which was identified by the Wilconxon signed rank test （P 〈0.05）. Conclusion： SWAN sequence can provide important information for preoperative grading of the cerebral gliomas. |
