[…] We pooled MCI subjects from ADNI-1 and ADNI-2 studies. Sex-differences in baseline demographic and cognitive variables were tested using either analysis of variance (ANOVA) or analysis of covariance (ANCOVA).Next we ran three mi […]

[…] ion can vary among different hardware and software platforms. Hence, for this proposed Web interface, the RSs are calibrated, making sure they always provide the same results before their deployment. ADNI renders FreeSurfer results calculated on FreeSurfer 5.1. In order to validate NWSI, a paired t test was performed to compare the values reported in the ADNIMerge file and the NWSI results. A tota […]

[…] s revealed a significant association between expression and genotype (effect size = 0.12, P = 0.004) in whole blood. We checked the relationship between APOE4 carrier status and GRN expression in the ADNI dataset but failed to detect a difference in GRN expression between APOE4 carriers and controls (T (613) = 1.43, P = 0.15). We also performed the converse analysis in the UCSF‐MAC cohort. Using C […]

[…] Preprocessed [18F]flortaucipir PET scans were downloaded from the ADNI Laboratory of Neuro Imaging (LONI; http://adni.loni.usc.edu) site. These scans were preprocessed using standard techniques in Statistical Parametric Mapping 8 (SPM8), including normalization to M […]

[…] r goal was to uncover which radiotracer demonstrated the stronger diagnostic accuracy and come to a recommendation of the tracer to use for AD. While both FDG and AV45 images were indeed available in ADNI for research purposes, typically in a clinical examination, FDG and AV45 will not be acquired during the same session, but rather one or the other. In a subsequent study, we will investigate the […]

[…] In our study, we used 77 subjects (41 AD and 36 LMCI) from ADNI GO public dataset, each with structural T1-w MR image. Data used in the preparation of this article were obtained from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) database (adni.loni.u […]
