摘　　要：目的探讨磁共振(MR)磁敏感加权成像(SWI)在脑胶质瘤术前分级中的应用价值。方法回顾性分析2015年12月-2018年2月我院收治的40例经手术病理证实的脑胶质瘤患者临床资料,所有患者术前均行常规MRI平扫、常规增强扫描及SWI检查,以病理分级结果为标准,评估MRI常规序列、SWI序列对脑胶质瘤术前分级的符合率。结果 SWI序列术前分级与病理分级的符合率为77.50%(31/40),明显高于MRI常规序列的55.00%(22/40),差异有统计学意义(P﹤0.05)。在SWI序列,随着肿瘤病理分级的提高,脑胶质瘤肿瘤内微出血体积逐渐增大(P﹤0.05),肿瘤内小血管数目逐渐增多(P﹤0.05)。结论 SWI序列在脑胶质瘤具有一定特征表现,可作为MRI常规序列的重要补充,以提高术前分级符合率。Objective To investigate the application value of magnetic resonance（MR）susceptibility weighted imaging（SWI） in preoperative grading of brain glioma. Methods The clinical data of 40 patients with brain gliomas confirmed by operation and pathology who were admitted to the hospital from December 2015 to February2018 were analyzed retrospectively. All patients underwent routine MRI plain scan, routine enhanced scan and SWI examination before operation. According to the results of pathological grading, the coincidence rates of MRI routine sequence and SWI sequence for preoperative grading of gliomas were evaluated. Results The coincidence rate of preoperative grading and pathological grading of SWI sequence was significantly higher than that of MRI routine sequence [77.50%（31/40） vs 55%（22/40）]（P〈0.05）. For SWI sequence, with the increase of pathological grade of tumors, the volume of microhemorrhage in gliomas increased gradually（P〈0.05）, and the number of micro-vessels in gliomas increased gradually（P〈0.05）. Conclusion The SWI sequence can be used as an important supplement to the routine MRI sequenceto improve the coincidence rate of preoperative grading of brain gliomas.
