PURPOSE
To assess the reliability of the Fazekas score on brain CT in acute stroke patients.
METHODS
Two raters evaluated the Fazekas score in 157 CT scans from consecutive patients with acute stroke.
RESULTS
The Fazekas scores on brain CT scans showed consistent (weighted κ, 0.73) and moderate (weighted κ, 0.56) interobserver agreement for periventricular and deep white matter areas, respectively. Intraobserver reliability was substantial for both areas (weighted κ, 0.85 and 0.8).
CONCLUSION
The Fazekas score on CT can be used to reliably grade white matter changes, and can be a useful tool when MRI is not available.
目的
评估急性卒中患者脑部CT的 Fazekas评分的可靠性。
方法
两名评估者对157例连续急性卒中患者的CT扫描进行Fazekas评分。
结果
脑部CT扫描的Fazekas评分在脑室周围和深部白质区域分别显示出观察者间的一致性（加权κ值为0.73）和中度一致性（加权κ值为0.56）。两个区域的观察者内可靠性都很高（加权κ值分别为0.85和0.8）。
结论
CT上的Fazekas评分可用于可靠地对白质变化进行分级，并且在无法进行MRI检查时可能是一个有用的工具。
