【摘要】：目的探讨磁敏感加权成像（susceptibility weighted imaging，SWI）血管结构半定量评分法对颅内胶质瘤分级的诊断价值。 方法回顾性分析36例（15例低级别胶质瘤和21例高级别胶质瘤）胶质瘤患者的影像资料，患者于术前行磁共振常规平扫、增强和SWI扫描，SWI原始图像经后处理后得到最小强度投影图(minimum intensity projection,MinIP)。采用盲法，两名高年资神经影像诊断医师分别观察SWIminIP图肿瘤内新生血管数目并进行评分，，分析两组胶质瘤血管评分有无差异。 结果15例低级别胶质瘤，6例血管评分为0分，9例血管评分为1分；21例高级别胶质瘤，18例血管评分为2分，2例血管评分为3分，1例血管评分为1分。低级别胶质瘤组与高级别胶质瘤组血管评分有统计学意义（Z值为-5.327，P值0.05）。 结论磁敏感加权成像血管结构半定量评分法有助于颅内高、低级别胶质瘤的初步分级诊断。
[Abstract]:Objective to evaluate the diagnostic value of magnetic sensitivity weighted imaging (susceptibility weighted imagingsSWI) in the diagnosis of intracranial gliomas. Methods the imaging data of 36 cases of gliomas (15 cases of low grade gliomas and 21 cases of high grade gliomas) were retrospectively analyzed. After post-processing, the minimum intensity projection (minimum intensity projectionMinIP was obtained. The number of neovascularization in glioma was observed by two senior neuroimaging diagnostics with blind method and the difference between the two groups was analyzed. Results in 15 cases of low grade glioma, 6 cases had 0 score, 9 cases had 1 score, 21 cases had high grade glioma, 18 cases had blood vessel score, 2 cases had 3 points, 1 case had blood vessel score, 1 case had blood vessel score. There was significant difference in blood vessel score between low grade glioma group and high grade glioma group (Z value -5.327 P value 0.05). Conclusion the semi-quantitative scoring method of vascular structure in magnetic sensitivity weighted imaging is helpful for the initial grade diagnosis of high and low grade intracranial gliomas.
