The purpose of this study was to compare predictive capabilities for postoperative lung function in non-small cell lung cancer (NSCLC) patients of the state-of-the-art radiological methods including perfusion MRI, quantitative CT and SPECT/CT with that of traditional method such as anatomical method (i.e. qualitative CT) and perfusion scan with SPECT. Correlation coefficient and the limits of agreement between predicted and actual postoperative lung function of perfusion MRI, quantitative CT and co-registered SPECT/CT were better than those of traditional methods. In conclusion, state-of-the-art radiological methods can predict postoperative lung function more accurately than traditional methods in NSCLC patients.
