Muscle perfusion may be studied using the BOLD technique. This method relies on an air-cuff to induce reactive hyperemia. However, oxygen in air is a paramagnetic molecule and whether an inflated air-cuff has an effect on T2* signal measurement is not known. This study attempts to answer this question and offers solutions to correct for aberrant T2* signal changes.
