The paper demonstrates a model-free method to calculate cerebral perfusion metrics using a step change in deoxyhemoglobin during reoxygenation, comparing results to conventional methods.

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

The paper compares hypoxia-induced deoxyhemoglobin and gadolinium as susceptibility contrast agents for cerebral perfusion imaging in healthy participants.

The paper demonstrates the feasibility of using rapid changes in blood oxygenation to simulate gadolinium contrast in perfusion MRI for flow metric calculation.
