| 摘 要： | 目的探讨320层CT灌注成像在窦旁脑膜瘤瘤周水肿中的价值。方法对18例窦旁脑膜瘤伴瘤周水肿患者进行CT灌注成像,计算并比较窦旁脑膜瘤瘤周水肿区及对侧正常脑组织的脑血流量(CBF)、脑血容量(CBV)、平均通过时间(MTT))。结果窦旁脑膜瘤瘤周水肿区的CBF和CBV明显低于对侧正常脑组织(P<0.05)。但窦旁脑膜瘤瘤周水肿区的MTT与正常脑组织比较差异无统计学意义(P>0.05)。结论窦旁脑膜瘤瘤周水肿区的CBV和CBF明显降低;CT灌注成像能定量脑膜瘤瘤周水肿的血流灌注状况。

| Abstract: | Objective To evaluate the value of 320-slice CT perfusion imaging in the peritumoral brain edema of parasagittal meningiomas.Methods Peritumoral brain edema was examined by CT perfusion imaging in 18 patients with parasagittal meningiomas.The cerebral blood volume(CBV),cerebral blood flow(CBF) and mean transit time(MTT) were calculated and compared between peritumoral brain edema and the contralateral normal brain tissues.Results CBF and CBV of peritumoral brain edema were signifiacantly lower than those of... |
