We describe a new application for imaging with computed tomography (CT) in which a quantifiable map of tissue perfusion is created and displayed by means of a colour scale. A rapid sequence of images is acquired without table movement immediately after a bolus intravenous injection of radiographic contrast medium. The rate of enhancement in each pixel within the chosen slice can then be used to determine perfusion. The technique provides a quantifiable display of regional perfusion combined with the high spatial resolution afforded by CT.
我们描述了计算机断层扫描（CT）成像的一种新应用，即通过颜色标度创建并显示组织灌注的可量化图。在静脉团注造影剂后，立即在不移动检查床的情况下快速采集一系列图像。然后，可以使用所选切片内每个像素的增强速率来确定灌注情况。该技术提供了区域灌注的可量化显示，并结合了CT所具备的高空间分辨率。
