Abstract
PurposeTo assess the reliability of the Fazekas score on brain CT in acute stroke patients. MethodsTwo raters evaluated the Fazekas score in 157 CT scans from consecutive patients with acute stroke. ResultsThe 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). ConclusionThe Fazekas score on CT can be used to reliably grade white matter changes, and can be a useful tool when MRI is not available.
