摘要
目的探讨内耳内听道及面神经的磁共振成像技术及临床应用。方法45例耳部MR检查正常者采用三维稳态结构相干序列(3D-constructive inference in the steady state,3D-CISS)和采用快速自旋回波序列(turbo-spin echo,TSE)作颞骨容积扫描,之后行最大信号强度投影(MIP)技术处理,进行图像对比。结果3D-CISS对螺旋板、前庭阶、鼓阶、椭圆囊、球囊的显示对比TSE具有显著性意义。结论3D-CISS对内耳内听道细微结构的显示优于TSE。
Objective： To investigate the magnetic resonance imaging （MRI） technique and dinieal application in facial nerves, inner ear and internal auditory cannal. Methods： 45 cases with normal MR images of ears were scanned by 3D- constructive inference in the steady state （3D- CISS） and turbo- spin echo （TSE）and the in,age qualities were compared. Results. The difference of detection rates was statistically significant for saccule, vestibular crest, utricle, scala vestibule, scala tympani and spiral lamina. Conclusion： 3D- CISS is better than TSE for detecting the anatomical structures of internal auditory and labyrinth.
