Figure 5. — Estimated amyloid burden against the gold standard value calculated using full PET time series for 25 testing set subjects using 4 different methods: (a) RT-SRTM where t = 20,50 min (ASL-derived R₁), (b) $SUVR - 1$ where t = 50,60 min, (c) SRTM where t = 0,30 min (PET data only, no C_R extrapolation), (d) RT-SRTM where t = 20,50 min (PET data only, extrapolated C_R). The grey-shaded region covers the 95% confidence interval in the regression.
