An apparatus was developed that enabled invasive
acquisition of renal pO2 in vivo simultaneously with
renal BOLD T2* measurements. We found excellent
agreement between renal pO2 and T2* measurements across
different renal physiologic states. Invasive renal
oxygenation measurements of pO2 are useful for
validating BOLD measurements and can help elucidate
factors that may confound the estimation of oxygenation
from T2* measurements.
