The observersf consistency for the ischemic signs by increase of deoxyhemoglobin on T2*-WI was evaluated by kappa statistic, and the quantified map of susceptibility effect was compared with T2*-WI and perfusion imaging. The ischemic sings can be used with acceptable consistency as clinical indices of acute ischemia and T2*-WI would be used as a clinical method to evaluate ischemic extent.
