This study introduces a cardiac-specific BOLD fMRI-based pulsatility index, validates its sensitivity to hypercapnia, and shows its correlation with vascular reactivity and venous blood volume.

The paper presents a computational framework to simulate BOLD fMRI signal formation in a synthetic human 3D cortical vasculature model, showing that human-specific features significantly affect the BOLD fingerprint.

This study investigates how echo train length (ETL) affects microvascular specificity in SE-EPI BOLD fMRI, showing increased macrovascular contamination with longer ETL durations.

This paper quantifies cerebral blood arrival times using hypoxia-mediated arterial BOLD contrast and applies it to assess collateral flow in patients.

The paper examines how medullary vein architecture affects white matter BOLD-CVR responses to CO2 using high-resolution MRI and finds moderate correlations between vessel frequency and hemodynamic parameters.

This study quantifies how macro- and micro-vascular compartments affect laminar BOLD fMRI responses under hypercapnic and hyperoxic conditions.

This paper develops a pipeline to correct lipid suppression and partial volume effects in MRSI data to generate high-resolution metabolite maps of central brain structures.
