We proposed a new method to evaluate the lung function
by measuring the time constant of oxygen consumption (T
O-C
)
in the lung with hyperpolarized xenon MR. It
demonstrated that such time constant has a significant
difference between COPD and healthy rats, and we believe
this parameter is helpful to quantify the oxygen
concentration in oxygen therapy of patients.
