Comparisons of early-frame ¹⁸F-florbetapir and ¹⁸F-florbetaben Whole Brain SUVR Profile. a) Regional averages are displayed as a continuous line to help visualize a whole brain SUVR profile for each tracer and to easily compare between the early-frame ¹⁸F-florbetapir and early-frame ¹⁸F-florbetaben regional SUVRs. b) A cosine similarity matrix between all early-frame 18F-florbetapir and 18F-florbetaben vector pairs. A table with anatomical regions corresponding to the numbers in this graph is included in the Supplementary Material (Additional file 1: Supplementary Table S6). AV45 = ¹⁸F-florebetapir, FBB = ¹⁸F-florbetaben
