Synopsis
In this study, we tried to use hyperpolarized (HP) 129Xe MR to explore pulmonary physiological compensatory mechanisms. With the increased Xe washout times, obvious changes of chemical shift, FWHM, RBC oscillation amplitude and the parameters extracted from MOXE model could be found. Our study demonstrates the feasibility of HP 129Xe MR for assessing pulmonary compensatory capacity, which would be helpful for understanding lung function changes caused by pulmonary diseases and early diagnosis.
