Diffusion weighted magnetic resonance imaging. a–b) Axial, c) sagittal and d) coronal diffusion weighted magnetic resonance imaging showed a very intense nodular structure in the right upper lobe, suspected to be a tumoural lesion. The lesion was removed surgically and adenocarcinoma was confirmed on histopathology. W. De Wever et al. breathe 2011;7:338-346 ©2011 by European Respiratory Society
