Blood and myocardial T1, T2 and T2* relaxation times were measured with room air and supplemental oxygen supplied by nasal cannula and a non-rebreather mask using current vendor protocols. Only left ventricular and atrial blood T1s were significantly different from room when oxygen was supplied using a non-rebreather mask. Use of supplemental oxygen can change measured cardiovascular relaxation values and subsequent derived values. If supplemental oxygen is used, one can measure blood relaxation times from the right side of the heart as they are unaffected.
