摘要

脑灌注成像提供了有关脑血流动力学状态的有用信息，这些信息与许多神经系统疾病有关，包括中风、癫痫和脑肿瘤。多种成像方式已被开发用于评估脑灌注，主要是通过使用不同的示踪剂来测量脑血容量和脑血流量。在这里，我们提供磁共振成像灌注技术的概述;灌注显像在成人脑卒中中的作用综述描述儿童期脑血流量的变化;并讨论灌注成像在小儿脑血管疾病和脑卒中中的相关性及未来发展方向。

Cerebral Perfusion in Pediatric Stroke: Children Are Not Little Adults.

Abstract: Cerebral perfusion imaging provides useful information about the hemodynamic state of the brain that is relevant to a number of neurologic conditions, including stroke, epilepsy, and brain tumors. Multiple imaging modalities have been developed to evaluate brain perfusion, primarily by the use of different tracers to measure cerebral blood volume and cerebral blood flow. Here, we provide an overview of magnetic resonance imaging perfusion techniques; summarize the role of perfusion imaging in adult stroke; describe changes in cerebral blood flow over childhood; and discuss the relevance and future directions of perfusion imaging in pediatric cerebrovascular disorders and stroke.
