Progression of visual-stimulus-evoked blood velocity response timing across the vascular network measured with individual-vessel phase-contrast fMRA

This paper measures blood velocity response timing across the vascular network using dynamic PC-fMRA, showing arterial and venous responses with distinct temporal delays.

Visual stimulus-evoked blood velocity responses in individual human posterior cerebral arteries measured with dynamic phase-contrast functional MR angiography

This study introduces a new fMRA method to measure dynamic blood velocity responses in human posterior cerebral arteries during visual stimulation, showing a 10% increase in velocity and indicating neurovascular coupling.
