Minimal time to achieve stable BP values. The complete 300-min data set was increasingly truncated to 240, 180, and 120 min. BP was calculated with MRTM2 (average values of the test and retest study) for striatum and extrastriatal regions (averaged for prefrontal cortex, temporal cortex, parietal cortex, occipital cortex, and thalamus). Each point represents the averaged estimated value from eight subjects, error bars representing standard deviation expressed as a percentage of the 300-min BP value.
