In this study, we analyzed T2* value in the mid-left
ventricular septum avid both normoxia and hyperoxia
among clinical cases with non-ischemic heart disease.
The oxygen-enhanced T2* cardiac magnetic resonance (CMR)
was promising to evaluate the myocardial blood-oxygen
dependent (BOLD) response to hyperoxia. The development
of quantitative evaluation technique for the oxygen
metabolism in human myocardium in vivo has opened up new
avenues for the study of the cardiac pathophysiology. To
our knowledge, this is the first clinical study that has
assessed the myocardial T2* response to hyperoxic
respiratory challenge by BOLD-CMR.
