Feasibility of pulmonary MRI for nodule detection in comparison to computed tomography
Abstract Background To assess the feasibility of various magnetic resonance imaging (MRI) sequences for the detection of pulmonary nodules by comparing the detection rate of computed tomography (CT). Methods Forty-two patients with pulmonary nodules detected by multi-slice CT (MSCT) were prospective...

The detection rate increased to 100% for lesions ≥6 mm. The C-VIBE had a lower overall detection rate (64.3%) of pulmonary nodules.
