Gadolinium-based blood volume (Gd-based BV) map generated between unenhanced and contrast-enhanced UTE-MRIs may have a potential for regional perfusion assessment like lung perfused BV map on dual-energy CT in patients with pulmonary diseases. We hypothesized that Gd-based BV map has a potential to regional perfusion assessment and postoperative lung function prediction as well as perfusion SPECT and/ or conventional CT methods in NSCLC patients. The purpose of this study was to directly compare the capability of Gd-based BV map for regional perfusion assessment and/ or postoperative lung function prediction in NSCLC patients with perfusion SPECT and conventional CT methods.
