59 E ect of flow on longitudinal tau PET Figure 3. Correlation plot of percentage (%) change in DVR vs SUVr80-100 in (a) SCD and (b) AD, in which the red line represents the line of identity. Bland-Altman plot of %change in DVR vs SUVr80-100 in (c) SCD and (d) AD. DVR = distribution volume ratio. SUVr = standardized uptake value ratio. SCD = subjective cognitive decline. AD = Alzheimer’s disease. Figure 4. Percentage change in (a) DVR and (b) SUVr80-100 relative to the true DVR values as a function of simulated flow changes for each binding condition. DVR = distribution volume ratio. SUVr = standardized uptake value ratio. SCD = subjective cognitive decline. AD = Alzheimer’s disease. 3
