摘　　要：目的 :探讨内耳膜迷路、面神经及位听神经的MRI技术方法及其临床应用价值。方法 :对 35例可疑内耳病变的患者采用平衡式三维梯度回波 (B TFE)及三维快速自旋回波T2 W序列 (T2 /3D/TSE)、轴位及斜矢状位扫描 ,最大信号强度投影 (MIP)、多平面投影 (MPR)法图像重建。结果 :所有内耳膜迷路、面神经及位听神经结构均得到了良好显示。其中 2 6例正常 ,9例异常。结论 :MRIB TFE和T2 /3D/TSE扫描序列及MIP、MPR重建技术 ,可很好地显示内耳结构及其微小病变 。Objective:To investigate the clinical application value of MRI scanning technique in inner ear structure and lesion.Methods:35 cases underwent axial and oblique sagital MRI scanning with B TFE and T 2/3D/TSE sequences.Images were reconstructed by maximun intensity projection (MIP) and multi planar reformation(MPR)technique.Results:All cases of membranous labyrinth of inner ear,facial nerve and acoustic nerve were clearly displayed.Of 35 patients,26 were normal,9 cases were abnormal.Conclusion:MRI B TFE sequence and T 2/3D/TSE scanning sequence and MIP MPR reconstruction technique have high clinical application value in diagnosing inner ear diseases.
