Academic
and social interest to radiation induced cancer development on CT examination
is increasing in the world. Since
1997, several investigators have suggested that pulmonary MR imaging on 1.5T
MR system has potential for nodule detection as substitution to CT. To the best of our knowledge, no one
directly compare the capability of non-contrast-enhanced (non-CE) pulmonary
MRI for pulmonary nodule detection between 1.5T and 3.0T MR systems. The purpose of this study was to
prospectively and directly compare the capability of non-CE pulmonary MR
imaging on 3.0T MR system for nodule detection than that on 1.5T MR system.
