Linear relationship between the simulated uptake ratios and the measured indexes of each investigated structure to each quantification methodology assessed. The results striatum cavities measured by manual method (a–c), automatized methods (d–i) and semi-automatized methods (j and k) were compared and fitted with the real ratios fill through quality metrics to accuracy and precision to each quantitative method assessed
