Impact of multi-echo ICA modeling decisions on motor-task fMRI analysis

This study compares ME-ICA denoising approaches in motor-task fMRI, finding that a conservative method better preserves task-related signal while reducing noise in high-motion scenarios.

Multi-echo BOLD fMRI improves cerebrovascular reactivity estimates in stroke

This study shows that multi-echo fMRI techniques improve cerebrovascular reactivity estimates in stroke patients by reducing noise and negative values.

Iterative delay correction improves breath-hold cerebrovascular reactivity mapping in clinical populations

This paper introduces an iterative delay correction method to improve breath-hold cerebrovascular reactivity mapping in clinical populations by adjusting the temporal search range for each voxel.

Quantitative mapping of cerebrovascular reactivity amplitude and delay with breath-hold BOLD fMRI when end-tidal CO2 quality is low

This paper develops methods to estimate cerebrovascular reactivity (CVR) amplitude and delay in breath-hold fMRI when PETCO2 data quality is low, using rescaled RVT and deep learning-predicted PETCO2.

Simultaneous cortical, subcortical, and brainstem mapping of sensory activation

This study maps sensory activation across the cortex, subcortex, and brainstem using whole-brain fMRI, showing distinct responses to hand and foot stimulation and differentiating small brainstem nuclei.
