摘要

目的:探讨多层螺旋CT灌注成像在正常人脑血流动力学定量研究中的价值。方法:选择24例正常成年人

常规头颅CT平扫后

选取基底节及其相邻层面行CT灌注成像检查

所得图像经CT灌注软件包进行后处理

获得灌注图像

测量感兴趣区的血流量、血容量及平均通过时间

并对其进行定量分析。结果:24例正常人基底节区灌注高于灰质区

灰质区灌注高于白质区。正常人灰质的CBF、CBV、MTT分别为（52.8±10.0）ml（/100g·min）、（2.7±0.6）ml/100g、（3.7±0.9）s;白质分别为（22.0±3.3）ml（/100g·min）、（1.3±0.4）ml/100g、（5±1.2）s。结论:CT灌注成像技术为测量脑血流动力学指标提供了一种新的影像方法。

Abstract

Objective:To explore the application value of multislice CT perfusion imaging in normal adult cerebral hemodynamics. Methods:Routine CT and multislice CT perfusion imaging were performed by selecting the basal ganglia slice and its adjacent slice in 24 normal adults

These scan dynamic images were peocessed with the CT perfusion software package.Cerebral blood flow(CBF)

cerebral blood volume(CBV) and mean transiting time(MTT) were measured within the specific regions of interest(ROI) of the brain

and quantitative analysis was performed. Results:A gradient of perfusion between gray matter and white matter showed on multislice CT perfusion imaging in normal adults.CBF

CBV

MTT were(52.8±10.0)ml/(100g·min)

(2.7±0.6)ml/100g

(3.7±0.9)s respedtively in the gray matter and(22.0±3.3)ml/(100g·min)

(1.3±0.4)ml/100g

(5±1.2)s respectively in the white matter. Conclusion:multislice CT perfusion imaging provided a new imaging method for measuring the cerebral hemodynamics.
