摘  要:
目的:探讨CT灌注成像(CTPI)对高级别胶质瘤的诊断价值。方法:高级别胶质瘤19例,常规CT扫描的基础上行CT灌注成像检查。分析灌注图像,测量肿瘤实质、瘤周水肿及对侧正常脑组织的脑血流量(CBV)和脑血容量(CBF),并对两组进行比较。结果:肿瘤实质与对侧正常脑组织的CBV、CBF值间均有统计学差异(P<0.05)。瘤周水肿与对侧正常脑组织的CBV、CBF值间均无明显差异。结论:CTPI对胶质瘤的鉴别诊断及分级具有临床实用价值。

摘  要:
Objective:To explore the diagnostic value of CT perfusion imaging in high-grade gliomas.Methods:19 high grade astrocytomas underwent conventional CT and CT perfusion imaging examination before operation.The perfusion images were analyzed respectively.The values of CBF and CBV were measured in parenchyma part, tumor edema and contralateral cerebral tissue, and the values were processed statistically.Results:The values of CBV and CBF between parenchyma part of glioma and contralateral normal part showed significant differences (P<0.05). There were no marked differences in CBF and CBV values between tumor edema and contralateral region.Conclusion:CT perfusion imaging is of great value in differentiating and grading gliomas in clinical procedures.
