Our study shows that hyperpolarized 129Xe MRI can
noninvasively detect the RILI. By using the CSSR
sequence and the model of xenon exchange to detect the
exchange time in blood and tissue, 129Xe MRI appears to
be able to quantitatively evaluate and monitor the
changes of lung functions, which is in agreement with
the pathological results.
