[Abstract] Objective: To explore the application of magnetic resonance imaging with three-dimensional volumetric interpolated breath-hold examination (3D-VIBE) sequence and STAR-VIBE sequence in displaying pulmonary nodules.Materials and Methods: Forty-two patients who were suspected with lung lesions and underwent chest CT and chest MRI were collected. Magnetic resonance imaging with 3D-VIBE sequence and STAR-VIBE sequence were performed using a 3.0 T magnetic resonance scanner. Magnetic resonance images were independently analyzed by two radiologists who owned more than five years working experience with CT images as a reference standard. The detection rates of pulmonary nodules in different MRI sequences were calculated, and the morphological features of pulmonary nodules were evaluated on magnetic resonance imaging using the 4-point scoring criteria.Results: Two hundred and fifty-eight pulmonary nodules were detected on CT images in 42 patients, 243 pulmonary nodules were detected on STAR-VIBE sequence (detection rate 94.2%), while 166 pulmonary nodules were detected on 3D-VIBE sequence (detection rate 64.3%). The detection rate of STAR-VIBE sequence was significantly higher than that of 3D-VIBE sequence, and detection rate increased to 100% for those pulmonary nodules with diameter ≥6 mm on STAR-VIBE sequence. The subjective scores of STAR-VIBE sequence were significantly superior to 3D-VIBE sequence in displaying morphological features of pulmonary nodules (all P<0.05).Conclusions: Compared with 3D-VIBE sequence, STAR-VIBE sequence not only improves the detection rate of pulmonary nodules, but also provides more information on the morphological features of pulmonary nodules.
