ComCat: Combating Covariate Effects in Brain Analysis

ComCat improves brain analysis by reducing unwanted variability from heterogeneous datasets, outperforming existing methods in brain age prediction across multiple datasets.

The Good, the Bad, and the Ugly: Segmentation-Based Quality Control of Structural Magnetic Resonance Images

This paper introduces a quality assessment framework for structural MRI images using tissue classification to identify and mitigate motion artifacts and other quality issues.

The Uniqueness of Human Vulnerability to Brain Aging in Great Ape Evolution

The paper compares age-related brain deterioration between humans and chimpanzees, finding a unique positive relationship between cerebral aging and cortical expansion in humans.

BrainAGE: Revisited and reframed machine learning workflow

The paper revises the BrainAGE method using Gaussian process regression, showing improved performance on UK Biobank data and disease-specific patterns in clinical samples.

Approximation of bone mineral density and subcutaneous adiposity using T1-weighted images of the human head

The paper proposes methods to approximate bone mineral density and subcutaneous adiposity from T1-weighted head MRI images and validates their reliability and correlation with DXA and MRI measurements.

CAT - A Computational Anatomy Toolbox for the Analysis of Structural MRI Data

The paper introduces CAT, a computational anatomy toolbox for structural MRI analysis, providing a comprehensive suite of tools for morphometric analyses with quality control and visualization features.

To Smooth or not to Smooth: Enhancing Specificity While Maintaining Sensitivity

The paper shows that omitting spatial smoothing in neuroimaging can improve regional specificity without reducing sensitivity, particularly for small-scale brain structures.

Chimpanzee Brain Morphometry Utilizing Standardized MRI Preprocessing and Macroanatomical Annotations

This study develops a chimpanzee brain reference template and processing pipeline to analyze structural MRI data, revealing age-related GM atrophy and hemispheric asymmetry patterns.
