BZ, borderzone regions; g, global; leuko, regions of leukoaraiosis (differences computed in the eight subjects with ARIC leukoaraiosis scores (Wong et al, 2002) of ⩾5); PIB, regions of peak PIB uptake (differences computed in the 11 subjects in whom peaks comprised at least 10 mL).

^aPercentage change calculated as the mean of the percent change in values for each subject.
