The SUVRs of 18F-BCPP-EF (A) and 11C-PiB (B) tracers and the relationships between them (C–E). The SUVR of 18F-BCPP-EF was significantly lower, and that of 11C-PiB (B) was higher in the 15-week-old SAMP10 mice than in the controls (A and B, *p < 0.05). A negative correlation between the binding of the two tracers was found in the 15-week-old SAMP10 mice (E). The dotted lines in E represent the 95% confidence intervals for the correlation. n = 6 for 15-week-old SAMR1 mice and n = 8 for 5-week-old and 15-week-old SAMP10 mice
