This study aimed to evaluate the capability of different non-enhanced MRI sequences for lung nodules assessment. Sensitivity and specificity from MR images were calculated, with CT regarded as golden standard. The sensitivities by T1-starVIBE, T1-VIBE, T2-fBLADE TSE and T2-SPACE were 79.79%, 75%, 88.3%, 89.89%, while the specificity were 100%, 83.33%, 33.33%, 53.33% respectively. In conclusion, for uncooperative patients who can’t hold their breath, T1-starVIBE and T2-fBLADE were advised because of the excellent ability to remove artifacts. T1-VIBE can applied to those who coordinate well. All those three sequences can be used for pulmonary nodules assessment and long-term follow-up in clinical.
