TRAECR: A Tool for Preprocessing Positron Emission Tomography Imaging for Statistical Modeling
Akhil Ambekar, Robert Zielinski, Ani Eloyan
The paper introduces TRAECR, a software tool that streamlines preprocessing of PET brain images—including registration, MRI‑PET co‑registration, brain extraction, and intensity har…
Causal Inference for Unobservable Multivariate Outcomes, with Applications to Brain Effective Connectivity
Haiyue Song, Ani Eloyan, Youjin Lee
Evaluating the causal effect of an intervention on multivariate outcomes is challenging when the outcomes are interdependent and derived rather than directly observed. Effective co…
Geometric Modeling of Hippocampal Tau Deposition: A Surface-Based Framework for Covariate Analysis and Off-Target Contamination Detection
Liangkang Wang, Akhil Ambekar, Ani Eloyan
We introduce a framework combining geometric modeling with disease progression analysis to investigate tau deposition in Alzheimer's disease (AD) using positron emission tomography…
Leveraging population information in brain connectivity via Bayesian ICA with a novel informative prior for correlation matrices
Amanda Mejia, David Bolin, Daniel Spencer +1
Brain functional connectivity (FC), the temporal synchrony between brain networks, is essential to understand the functional organization of the brain and to identify changes due t…
