In recent years, the broad introduction of fast multidetector computed tomography (CT) systems and the availability of commercial software for perfusion analysis have made cerebral perfusion imaging with CT a practical technique for the clinical environment.
This article reviews the use of CT for imaging cerebral perfusion, highlighting its advantages, disadvantages and limitations, and draws comparisons between perfusion CT and magnetic resonance imaging. The authors performed 96 perfusion CT examinations in the last one and a half years. Future technical developments in multi-slice CT systems may diminish the current limitations of limited spatial coverage and radiation burden. Yet CT is often not perceived as a technique for imaging cerebral perfusion.
The technique is widely available at low cost, accurate and easy to perform. Perfusion CT is particularly applicable to those clinical circumstances where patients already undergo CT for other reasons, including stroke.
近年来，快速多排探测器计算机断层扫描（CT）系统的广泛应用以及用于灌注分析的商业软件的出现，使得CT脑灌注成像成为临床环境中一种实用的技术。
本文回顾了CT在脑灌注成像中的应用，强调了其优点、缺点和局限性，并对灌注CT和磁共振成像进行了比较。作者在过去一年半中进行了96次灌注CT检查。多层CT系统未来的技术发展可能会减少当前空间覆盖受限和辐射负担方面的局限性。然而，CT通常不被视为一种脑灌注成像技术。
该技术成本低廉，广泛可用，准确且易于操作。灌注CT特别适用于那些患者因其他原因（包括中风）已经接受CT检查的临床情况。
