Physiological Confounds in BOLD‐fMRI and Their Correction

NMR in Biomedicine, Volume 38, Issue 7, Page 1-27, July 2025.
This graphical abstract depicts physiological confounds in BOLD‐fMRI from respiratory and cardiac sources, categorized by frequency, and highlights their effects on brain regions through various mechanisms. The figure contrasts model‐based correction methods with data‐driven techniques, outlining the strengths and limitations of each approach in ...

Equivalence of Plasma and Serum for Clinical Measurement of p‐tau217: Comparative Analyses of Four Blood‐Based Assays

Journal of Neurochemistry, Volume 169, Issue 7, July 2025.
This study evaluated the use of serum, rather than the commonly used plasma, to measure phosphorylated tau (p‐tau) 217—a key biomarker for Alzheimer's disease. Using four different assays, including three commercial and one developed at the University of Pittsburgh, we compared p‐tau217 levels in matched serum and plasma samples from two cohorts, with ...

Cross‐Modality Image Translation of 3 Tesla Magnetic Resonance Imaging to 7 Tesla Using Generative Adversarial Networks

Human Brain Mapping, Volume 46, Issue 9, June 15, 2025.
Generative adversarial networks (GANs) were used to translate 3T MRI images to synthetic 7T MRI, offering improved contrast and resolution. This method facilitates cross‐modality harmonization, allowing efficient use of heterogeneous MRI data without compromising existing datasets.

The adverse effect of gradient nonlinearities on diffusion MRI: From voxels to group studies

NeuroImage, 2020
Nonlinearities of gradient magnetic fields in diffusion MRI (dMRI) can introduce systematic errors in estimates of diffusion measures. While there are correction methods that can compensate for these errors, as presented in the Human Connectome Project ...

Big Data, Small Bias: Harmonizing Diffusion MRI‐Based Structural Connectomes to Mitigate Site‐Related Bias in Data Integration

Human Brain Mapping, Volume 46, Issue 9, June 15, 2025.
As big data drives collaboration across institutions, this study tackles the challenge of merging multi‐site structural connectome data while minimizing site‐related biases. We present a pioneering harmonization framework, MATCH, tailored to structural connectomes, offering essential guidelines to facilitate multi‐site data integration to yield more ...

Harmonization of Structural Brain Connectivity Through Distribution Matching

Human Brain Mapping, Volume 46, Issue 9, June 15, 2025.
Our distribution‐matching approach to harmonization outperforms ComBat in harmonizing structural brain connectivity across multi‐site dMRI studies, enhancing correlation with cognitive scores and age. This method improves reliability and comparability in neuroscientific research combining data from different sources.

Predictability of intelligence and age from structural connectomes.

PLoS ONE
In this study, structural images of 1048 healthy subjects from the Human Connectome Project Young Adult study and 94 from ADNI-3 study were processed by an in-house tractography pipeline and analyzed together with pre-processed data of the same subjects ...
