【摘要】 目的应用磁敏感加权成像(SWI)探讨肿瘤内出血量与脑胶质瘤病理分级的关系,初步评价SWI技术对脑胶质瘤恶性程度分级的价值。方法30例脑胶质瘤患者均接受SWI序列扫描。用测量软件逐层测量SWI序列所显示的出血成分面积。比较高度恶性胶质瘤组与低度恶性胶质瘤组在SWI序列上显示的肿瘤出血率及出血量。结果30例脑胶质瘤患者,SWI序列显示的高度恶性胶质瘤组的出血率(80.00%)大于低度恶性胶质瘤组(46.67%),但差异无统计学意义(P=0.064)。高度恶性胶质瘤组在SWI序列上显示的出血量大于低度恶性胶质瘤组,差异有统计学意义(Z=-2.275,P=0.026)。结论利用SWI序列显示的脑肿瘤内出血量对术前脑胶质瘤分级诊断有一定价值。更多还原

【Abstract】 Objective To explore the relationship between the amount of bleeding and the histopathologic grade of cerebral glioma with susceptibility weighted imaging (SWI),so that to assess the diagnostic value of SWI in grading cerebral glioma.Methods Totally 30 patients with cerebral glioma underwent SWI.The area of hemorrhage of every slice displayed in SWI was measured with software.The rate and amount of bleeding were compared between high and low grade tumors.Results There was no statistical significance in the incidence of detected bleeding on SWI (P=0.064),though it was higher in highly malignant group (80.00%) than that in low grade group (46.67%),while there was statistical significance in the amount of bleeding detected on SWI (Z=-2.275,P=0.026) between highly malignant group and low grade group.Conclusion The amount of tumor hemorrhage displayed in SWI is valuable for the preoperative grading of cerebral glioma.更多还原
