| 摘 要： | 目的探讨矢状窦旁脑膜瘤320排CT灌注成像方法,评估其对该脑膜瘤诊治的价值。方法对38例矢状窦旁脑膜瘤患者术前行320排CT检查,将容积数据导人Toshiba公司的4D-Perfusion专门软件包进行后处理,得出灌注图像及参数,包括脑血流量(CBF)、脑血容量(CBV)、平均通过时间(MTT)和达峰时间(TTP)。结果 38例灌注图像均可以清晰显示肿瘤的大小、轮廓。瘤组织CBF、CBV、TTP分别是(778.1±104.2)ml/100ml·min、(81.7±20.4)ml/100ml、(18.9±1.1)s,均明显高于正常脑组织(P<0.01);瘤组织MTT是(7.4±2.2)s,与正常脑组织无明显差别(P>0.05)。灌注成像与CTA图像融合能清晰显示供血动脉、肿瘤组织、脑组织、引流静脉及与矢状窦的关系。结论 320排CT灌注成像为矢状窦旁脑膜瘤血流灌注的定量研究提供了新的方法,对了解肿瘤内部血流状态及微血管的改变有一定的价值。灌注成像与CTA图像融合对矢状窦旁脑膜瘤手术有指导意义。

| Abstract: | Objective To investigate the clinical value of 320 rows CT perfusion imaging(PI) to the diagnosis and treatment of the parasagittal meningiomas(PSM).Methods The preoperative 320 rows CT PI was performed in 38 patients with PSM.The volume data were calculated by 4D-Pefusion software made by Toshiba Corporation in workstation to get the perfusion images and parameters including cerebral blood flow(CBF),cerebral blood volume(CBV),mean transit time(MTT) and time to peak(TTP).ResultsThe tumors and the difference... |
