Clinical Application of 3.0T MR Imaging in the Diagnosis of Inner Ear Lesions

Objective:To discuss the value of fluid-attenuated imaging with 3.0T MRI in the diagnosis of inner ear lesions.Methods:The imaging materials of fluid-attenuated MR imaging in 35 patients were analyzed.Routine T2W and 3D-FIESTA sequences were used with a 3.0T MR scanner.The fluid-attenuated signals of the inner ear region were acquired and the raw data were transferred to a MR workstation for 3-dimensional reconstruction.Results:Detail anatomy of internal auditory canal and membranous labyrinth of inner ear could be showed satisfactorily by 3D-FIESTA sequence.The maximum intensity projection(MIP)technique can display the membranous labyrinth of inner ear stereoscopically.The 3-dimensional anatomic relationship of membranous labyrinth could be demonstrated by multi-planar volume rendering(MPVR).Conclusion:Fluid-attenuated MR Imaging of membranous labyrinth can provide reliable information of inner ear anatomy,which is helpful in clinical application.
