ModelArray is an R package for efficient statistical analysis of fixel data, supporting linear and nonlinear models with reduced memory usage.

This paper introduces a method to analyze intermodal coupling between multiple brain imaging modalities and applies it to study neurodevelopmental patterns in adolescents.

This study examines how cerebral blood flow and fMRI fluctuations are coupled in youth, finding age-related decreases, sex differences, and links to executive function.

This paper develops an automated method to detect paramagnetic rim lesions in MS using MRI data and radiomic features with a random forest classifier.

TAPAS is an automated thresholding algorithm for segmenting brain lesions in MS using probability maps, reducing error and bias compared to manual and group-level thresholding.

MIMoSA improves automated white matter lesion segmentation in multiple sclerosis by integrating multimodal MRI data through inter-modal coupling regression and local logistic regression.
