O2-enhanced MRI can assess regional ventilation and alveolocapillary gas transfer of molecular oxygen. However, none of these studies have examined the quantitative and qualitative capabilities of O2-enhanced MRI for evaluation of candidates for lung volume reduction surgery (LVRS), and compared with that of evaluation by means of thin-section MDCT and perfusion SPECT/CT. The purpose of the study was thus to prospectively and directly compare the quantitative and qualitative capabilities of O2-enhanced MRI, thin-section MDCT and perfusion SPECT/CT to predict therapeutic outcomes for LVRS candidates.
