Clinical Correlates of FDG PET and DaT Factors in Heterogenous Clinical Sample

Overall, our approach identified distinct FDG and DaTscan factors using clinical ratings when assessed within the same statistical model. These factors were differentially related to amyloid positivity, cognition, functioning, and select symptom measures. This approach may hold utility in clinical datasets which are often comprised of more complex patients and may rely on clinical reads of PET and DaTscan.
