Hypercapnia and hyperoxia, induced using targeted gas
challenges, may be used to probe physiological effects
related to the Blood Oxygen Level Dependent (BOLD)
signal. Multi-echo BOLD data is acquired allowing
changes in T2* and S0 parameters in response to
breathing challenges to be examined. Results are
explained in the context of physiological phenomenon.
