This study examines the effects of therapeutic acute intermittent hypoxia on cerebrovascular function in healthy individuals and finds no significant changes in whole-brain blood flow or reactivity.

This study assesses cerebral blood flow responses to hypoxia and hypercapnia using MRI, finding poor reliability in hypoxic CVR and paradoxical responses not explained by CO2 changes.

The paper examines individual variability in the relationship between resting-state fMRI metrics and cerebrovascular reactivity (CVR) using longitudinal data from 7 subjects with 10 sessions each.

This study compares hemodynamic delay estimates between resting-state and breathing-task fMRI data in healthy adults, finding poor overall agreement but improved agreement in specific brain regions.

This paper compares alternative reference signals for mapping cerebrovascular reactivity using breath-hold task BOLD fMRI, showing that RVT and GM-BOLD can produce comparable CVR maps when PETCO2 quality is insufficient.

The paper investigates how data acquisition and modelling choices affect the relationship between baseline cerebral blood flow and BOLD cerebrovascular reactivity, finding that breathing task data and lag-optimization improve correlations.

This paper modifies a resting-state fMRI protocol by adding breathing tasks to improve cerebrovascular reactivity (CVR) characterization and hemodynamic lag estimation.

This paper introduces a breath-hold calibrated fMRI method to map cerebral oxygen metabolism without requiring respiratory equipment or long acquisition times.

This study evaluates ICA-based denoising strategies for improving CVR estimates in multi-echo BOLD fMRI during breath-hold tasks, finding that a conservative ICA model reduces motion effects best.

This study uses dual-calibrated fMRI to show reduced oxygen supply and consumption in MS patients without changes in oxygen extraction, suggesting impaired oxygen utilization or transfer.
