磁共振3D-VIBE序列和STAR-VIBE序列对肺结节显示能力的比较研究
Comparative study of magnetic resonance imaging with 3D-VIBE sequence and STAR-VIBE sequence on pulmonary nodule
摘要
Abstract
Objective:To explore the application of magnetic resonance imaging with threedimensional 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, 243pulmonary nodules were detected on STAR-VIBE sequence (detection rate 94.2％), while 166pulmonary 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 to3D-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.关键词
