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.
