Left panels: box-plots for a gray/white-matter contrast, b sharpness, and c relative noise index obtained with current 2-mm reconstruction processes of analog and digital PET images and with a 1-mm reconstruction process developed for digital PET images. Right panel: corresponding parameters provided by a visual analysis from experienced physicians (sum-scores for contrast, spatial resolution, and noise level)
