目的：探讨磁敏感加权成像(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例低级别和21例高级别)胶质瘤患者的影像资料,患者于术前行 MR 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(MinIP)。采用盲法,2名高年资神经影像诊断医师分别观察后处理 SWIminIP 图肿瘤内新生血管数目进行评分,分析2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SWI 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。

Objective To investigate the diagnostic value of susceptibility weighted imaging (SWI)semiquantitative assessment of pathological vascularity in grading cerebral gliomas.Methods Images of thirty-six patients with gliomas(1 5 low-grade and 21 high-grade gliomas)were obtained before therapy.Standard clinical MR imaging and SWI were performed at GE 3.0T scanner.All SWI postprocessed images were reviewed independently by two neuroradiologists and the number of vessels in tumor region were scored. Tumor were graded according to the World Health Organization classification.Results In 1 5 cases of low-grade glioma,semiquanti-tative assessment of pathological vascularity scored 0 in 6 cases,1 in 9 cases.In 21 cases of high-grade gliomas,semiquantitative as-sessment of pathological vascularity scored 2 in 18 cases,3 in 2 cases,1 in 1 case.There was a statistical significance between low-grade and high-grade gliomas(Z =-5.327,P <0.05).The grade of intratumoral pathological vascularity detected on SWI was asso-ciated with tumor grade.Conclusion It is usefull that SWI semiquantitative assessment of pathlogical vascularity in grading cerebral gliomas between low-grade and high-grade.
