Abstract (in Japanese) (See Japanese page) 
(in English) t-PA(tissue plasminogen activator) thrombolysis is an effective clinical treatment for the acute cerebral infarction cerebral caused by blood clots. Because of the risk of hemorrhage when t-PA materials were admitted the guideline of the treatment is requiring to deny the existence of cerebral hemorrhage and widespread Early CT sign (ECS) on CT images. In this study, we have constructed normal brain models by using 60 normal brains X-ray CT cases. We obtain the Z-score based on the statistical model to detect ECS. The sensitivity of the detection for 23 cases of cerebral infarction with ECS was 90.3%. We performed receiver operating characteristic (ROC) analysis to evaluate the usefulness the scheme. Average of the-area-under-curve (AUC) from 6 readers was increased from 0.767 to 0.935 when they used the CAD results.
