目的：探讨3．0 T MR的PROPELLER FSE T2WI与薄层3D－FIESTA重建图像对内听道细微结构显示情况的对比分析，探讨PROPELLER FSE T2WI提高内听道图像质量的作用。方法使用GE MR7503．0 T 超导MR成像仪，包括132例进行了双侧内听道MR检查的患者，分别进行斜矢状位（与内听道垂直） PROPELLER FSE T2WI与3D－FIESTA技术的两次采集，再将3D－FIESTA图像与前者完全一致的层面进行内听道垂直重建。2名放射医生采用一个4级标准评价内听道细微解剖结构总体图像质量，对比分析比较PROPELLER与3D－FIESTA技术重建同层面图像对内听道细微结构显示情况。图像之间的对比采用Wilcoxon秩和检验。结果 PROPELLER FSE T2WI组总体图像质量显著优于3D－FIESTA组（P＜0．05）。结论内听道MRI应用PROPELLER FSE T2WI斜矢状位扫描在显示内听道内细微结构方面明显优3D－FIESTA重建图像，可以提高图像质量，但不能任意角度重建。

Objective To compare the image quality of FSE T2WI PROPELLER and 3D-FIESTA imaging of the internal auditory canal...Methods FSE T2WI PROPELLER and 3D-FIESTA examinations of the internal auditory canals were performed on 132 patients using a 3T MR scanner..The image quality was qualitatively evaluated by two radiologists and compared using the Wilcoxon signed rank test. Results The images quality of FSE T2WI PROPELLER was significantly better than that of the reconstructed images of 3D-FIESTA (P<0.05). Conclusion The FSE T2WI PROPELLER technique is superior to reconstructed 3D-FIESTA for assessing the internal auditory canals.
