结论：临床磁共振成像仪的最新进展，如3特斯拉，多通道相控阵线圈和新的脉冲序列，允许评价内耳液体环境的细微变化和血液-谷胱甘肽屏障的破坏。鼓室内注射Gd-DTPA可以通过成像检测患者的内淋巴积水。目的：描述内耳MRI的现状和未来的发展方向。材料与方法：根据我们的经验和文献研究，简要回顾了内耳MRI的历史和最新发展。结果如下：3D-FLAIR技术可以检测到许多内耳疾病中以前无法观察到的异常，例如突发性耳聋，耳硬化症，红斑狼疮，腮腺炎和Ramsay-Hunt综合征。影像学技术，适应症，并在鼓室内注射GdDTPA后，内淋巴积水的可视化研究结果进行了讨论。这一过程使可视化的内淋巴积水在体内。最后介绍了最新发展的3D-真实红外技术和32通道线圈的应用。
Conclusion: Recent advances in clinical MR imagers, such as the 3-Tesla, multi-channel phased-array coil and novel pulse sequences, allow the evaluation of subtle alterations in the inner ear fluid environments and breakdown of the blood-labyrinthine barrier. Intratympanic injection of Gd-DTPA allows the imaging detection of endolymphatic hydrops in patients. Objectives: To describe the current status of inner ear MRI and future directions for imaging. Materials and methods: Based on our experiences and literature research, a brief review of the history and recent developments of inner ear MRI is presented. Results: The 3D-FLAIR technique can detect abnormalities that could not be visualized previously in many inner ear diseases, such as sudden deafness, otosclerosis, lupus erythematosus, mumps, and Ramsay-Hunt syndrome. Imaging techniques, indications, and findings for the visualization of endolymphatic hydrops after intratympanic injection of GdDTPA are also discussed. This procedure enabled the visualization of endolymphatic hydrops in vivo. Newly developed 3D-real IR techniques and utilities of 32 channel coil are also presented.
