The purpose of our study was to investigate the technical feasibility of CODE(Concurrent Dephasing and Excitation) MRI in human lung. 1.3mm3 isotropic voxel 3D radial CODE imaging was performed in three healthy adult volunteers on 3.0 T MR system. An overall image quality of CODE was graded good to excellent. Pulmonary vessels were consistently traceable from central to subpleural area in whole lung. Thin bronchial walls were traceable from main bronchus to segmental bronchi with mild motion and streak artifacts on CODE. Lobar fissures were also identifiable. CODE MRI was techinally feasible in human lung on a clinical scanner.
