  1. Comparison of Bland Altman analysis for average difference (bias) and the limits of agreement between the semi-automated method and three automatic techniques according to the scanner type where they were performed. Only the three automatic techniques that did not show significant difference from the semi-automated in the overall analysis were included in this subanalysis. BCT= Background corrected technique, 8 SD= 8 standard deviations, FWHM= Full Width at Half Maximum
