| 摘 要： | 目的：探讨320排全脑动态容积CT血管造影及灌注成像在烟雾病中的应用价值。方法：18例烟雾病患者均行320排全脑动态容积CT扫描，并利用容积再现（VR）技术进行图像重组且采用电影模式观看，同时完成全脑灌注成像检查。结果：所有病例均获得良好的平扫容积图像、动态DSA图像及全脑灌注图像，均清晰显示发生狭窄、闭塞的颈内动脉及颅底异常血管网，其中双侧颈内动脉闭塞9例，单侧颈内动脉闭塞2例，单侧大脑中动脉闭塞7例，侧支血管表现为相应血管及其分支的粗大、增多及迂曲延长。全脑灌注图像中，显示平均通过时间（MTT）延长，为0.5~13.0s；局部脑血流量（rCBF）下降10例，降低幅度为26.0%~54.5%；局部脑血容量（rCBV）显示有8例在正常范围内，4例出现不同程度的降低（30.0%~68.5%）。结论：320排全脑动态容积CT成像可以动态观察颅内血管的形态及动态血流信息，全脑灌注图像可以量化评价烟雾病患者全脑灌注情况，真正实现了全脑一站式容积扫描，对于烟雾病的诊断和评价脑组织血供具有极高的临床应用价值。

| Abstract: | Objective: To evaluate the value of 320-slice whole brain dynamic volume CT angiography and CT perfusion imaging in moyamoya disease.Methods: Eighteen cases with moyamoya disease were examined with 320-slice whole brain dynamic volume CT.Imaging data were generated with volume rendering reconstruction and display in cine mode,and complete CT perfusion imaging were performed simultaneously.Results: We succeeded in obtaining plain images of whole-brain,dynamic CTA and whole-brain perfusion images in 18 patien... |
