Figure 3. Comparison of Alzheimer's Disease Neuroimaging Initiative (ADNI)–defined CSF cutpoints to T807 standardized uptake value ratio (SUVR).

Figure 3

Shaw et al.23 identified a CSF total tau:CSF β-amyloid 1–42 (Aβ42) ratio cutpoint of >0.39 (A, B) and a CSF Aβ42 <192 pg/mL cutpoint (C, D) for individuals more likely to progress from mild cognitive impairment to Alzheimer disease dementia in the ADNI sample. These cutpoints are shown in relation to total cortical (A, C) and inferior temporal (B, D) T807 SUVR. Aβ = β-amyloid.
