✦ Synopsis
Eight radiologists interpreted body CT images of 30 cases using a viewing station (six 17-in. monitors, 1024 £ 1280). Using two different display methods, zoom-and-pan' and browse-and-paste', the readers described the presence or absence of liver tumors using a ®ve-point rating scale and temporal changes between the current and previous studies using a seven-point rating scale. There was no signi®cant difference in kappa values for tumor detection between the two display modes. However, in describing temporal changes, the kappa value of the browse-and-paste was signi®cantly lower than that of zoom-and-pan p , 0:01: Browse-and-paste may have the disadvantage of greater interobserver variation.
