This study investigates why asymmetric spin echo qBOLD overestimates deoxygenated blood volume and finds diffusion effects and vessel size dependence contribute to the error.

This paper applies streamlined-qBOLD to acute stroke patients to quantify brain oxygenation parameters and their relation to tissue outcomes.

This study measures CBF-CBV coupling in different vascular compartments during neural activation and reports coupling constants for total and arterial CBV.

This study reduces cerebrovascular reactivity mapping scan time from 7-12 minutes to 3-5 minutes using a sinusoidal stimulus, maintaining reliable CVR magnitude estimates.
