| 目的 比较星形堆叠容积内插屏气(Star-VIBE)与T1-容积内插屏气(T1-VIBE)MRI显示周围型肺癌的价值。方法 前瞻性对52例周围型肺癌患者共56个病灶行胸部Star-VIBE和T1-VIBE MR检查。基于2种序列图像观察形态学征象并进行主观评分;测量病灶最大径、信噪比(SNR)及对比度噪声比(CNR);以CT为参考,比较Star-VIBE and T1-VIBE MRI显示周围型肺癌的价值。结果 Star-VIBE MRI显示毛刺征、分叶征、胸膜凹陷征和晕征优于T1-VIBE(P均＜0.05)。Star-VIBE MRI的CNR及SNR均显著高于T1-VIBE(P均＜0.001);2种 MRI之间及其与CT所示病灶最大径之间差异均无统计学意义(P均＞0.05)。结论 Star-VIBE MRI显示周围型肺癌优于T1-VIBE。 |

| Objective To compare the value of stack-of-stars-volumetric interpolated breath-hold examination (Star-VIBE) and T1-volumetric interpolated breath-hold examination (T1-VIBE) MRI for displaying peripheral lung cancer. Methods Fifty-two patients with 56 peripheral lung cancer were prospectively enrolled, and chest Star-VIBE and T1-VIBE MRI were acquired. The morphological features were observed, and the subjective scores were recorded. The maximum diameter, signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of lesions were measured based on Star-VIBE and T1-VIBE MRI, respectively. Taken CT as the references, the value of Star-VIBE and T1-VIBE MRI for displaying peripheral lung cancer were compared. Results Star-VIBE MRI had higher scores for displaying spiculation sign, lobulation sign, pleural depression sign and halo sign than T1-VIBE (both P＜0.05). CNR and SNR of Star-VIBE MRI were significantly higher than those of T1-VIBE (both P＜0.001). No significant difference of the maximum diameter of lesions measured based on Star-VIBE and T1-VIBE MRI compared with CT was found, nor between Star-VIBE and T1-VIBE MRI (all P＞0.05). Conclusion Star-VIBE MRI had better value for displaying peripheral lung cancer than T1-VIBE. |
