We hypothesize that Non CE-perfusion MRI based on fresh blood imaging (FBI) technique at 3T system can accurately assess regional perfusion difference, and predict postoperative lung function in NSCLC patients, when compared with perfusion scan (Q scan), thin-section MDCT and dynamic CE-perfusion MRI. The purpose of this study was to prospectively and directly compare capabilities of regional perfusion assessment and prediction of postoperative lung function in NSCLC patients among Q scan, thin-section CT, dynamic CE-perfusion MRI and non-CE-perfusion MRI.
