解读AAN发布的《DWI和PWI在缺血性卒中的诊断价值-循证指南》

Evidence-based guideline:The role of diffusion and perfusion MRI for the diagnosis of acute ischemic stroke:explanation and viewpoint

近期,美国神经病学学会(AAN)治疗与技术评定小组发布了《磁共振扩散加权成像(DWI)和灌注加权成像(PWI)在缺血性卒中的诊断价值-循证指南》(以下简称《指南》),《指南》以循证医学证据为基础,对相关研究试验进行回顾分析,并得出具有指导意义的6条推荐意见。本文对《指南》的主要内容进行介绍,对其采用的相关循证医学依据进行解读。

Recently, Therapeutics and Technology Assessment Subcommittee of the American Academy of Neurology reported the Evidence-based guideline： The role of diffusion and perfusion MRI for the diagnosis of acute ischemic stroke. The guideline retrospectively assessed the evidence for the use of diffusion-weighted imaging （DWI） and perfusion weighted imaging （PWI） in the diagnosis of patients with acute ischemic stroke, and provided 6 pieces of recommendations. In this article, the main contents of the guideline and its related evidences were reviewed and evaluated.
