CT技术在评估急性缺血性脑卒中患者侧支循环中的应用

CT in evaluating cerebral collateral circulation of acute ischemic stroke patients

脑侧枝循环在急性缺血性脑卒中的临床诊疗中非常重要,是急性缺血性脑卒中的治疗方案选择的重要依据,也能较好的预测患者的预后,因此使用影像学方法快速准确的确定缺血性脑卒中患者的侧枝循环状态至关重要,本文将系统的回顾目前临床实践和研究中常用的CT在缺血性脑卒中患者中评价侧枝循环的各种技术及其临床应用,包括单时相CT血管造影、多时相CT血管造影、以及CT灌注成像技术。

Cerebral collateral circulation is important in the treatment of acute ischemic stroke.Collateral circulation is a major aspect that physicians would consider to decide the treatment of acute ischemic stroke and a good indicator of patient prognosis.Thus,it is important to accurately evaluate collateral circulation of acute ischemic stroke patients.This paper will review the techniques and clinical applications of CT in collateral circulation assessment,including single-phase CT angiography,multi-phase CTA,and CT perfusion.
