Cerebral perfusion metrics calculated directly, model-free, from a hypoxia-induced step change in deoxyhemoglobin

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.

Quantifying cerebral blood arrival times using hypoxia-mediated arterial BOLD contrast

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

Cerebral perfusion imaging: Hypoxia-induced deoxyhemoglobin or gadolinium?

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

Perfusion MRI using endogenous deoxyhemoglobin as a contrast agent: preliminary data

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