Fig. 5.

Plot of [¹⁸F]flutemetamol vs. visual rating for all subjects. Black triangles indicate a Flute(+) rating by both SUVR and visual ratings, black circles indicate a Flute(−) rating by both SUVR and visual ratings, and gray triangles indicate a Flute(+) rating by SUVR and a Flute(−) visual rating. Points for subjects with a clinical AD diagnosis are under-struck with a red box. The line is the result of a linear regression over all 23 subjects (y = 0.31x + 1.16; R² = 0.72).
