内耳

The elastic properties of the guinea pig organ of Corti were investigated using atomic force microscopy in this study for mechanical modeling of the organ of Corti.

应用原子力显微镜分析内耳螺旋器不同部位的弹性特征。

It means that people are born deaf and this is generally caused by the malformations of the inner ear.

这意味着，人人生而聋，这是通常所造成的畸形的内耳。

3D-FIESTA sequence can precisely show structures inner ear and internal auditory canal, therefore, it is of high value in clinical application.

3D-FIESTA序列对内耳及内听道的结构显示清晰，具有较高的临床应用价值。

The onset of BPPV may relate to ischemic internal ear but is not relevant with gender and age.

内耳缺血可能与BPPV发病有关，但BPPV发病在不同性别、年龄之间差异无显著性。

Objective: To study the technical and clinical application of MRI of inner ear and internal auditory canal using 3D-FIESTA sequence.

目的：探讨3D-FIESTA序列内耳及内听道成像技术及其临床应用价值。

HRCT can show clearly the structure of the external ear, middle ear and internal ear.

结果：HRCT能清楚显示外耳、中耳、及内耳结构。

The external ear and the middle ear are the conductive device of sound waves. The internal ear functions to receive the sound wave and locate it.

外耳和中耳是声波传导的装置，内耳则除接受声波外，尚有位觉功能。

Methods: Volume scans of temporal bone was performed in 25 patients (50 ears) with 3D-FIESTA sequence. Post-procession with multiplanar reformation, maximum intensity projection and virtual endoscape were operated to evaluate the ability of 3D-FIESTA sequence to show anatomic structures and lesions in inner ear and internal auditory canal.

用GE signa 3.0T超导型磁共振对25例共50耳应用3D-FIESTA序列做颞骨三维容积扫描，采用多平面重组、最大强度投影及仿真内窥镜行后处理，观察3D-FIESTA序列对内耳及内听道内各解剖结构的显示。

Methods:Internal ear and complications of 160 patients with NPC were examined pre-radiotherapeutically,and middle ear pressuresof these patients were measured.Results:Sixty patients with secretory otitis media accounting for 37.5﹪(60/160) of all the patients and 19.3﹪(62/320) of all the ears.

调查160例NPC患者放疗前一周内耳部并发症情况，并测量其中耳压力，另选择80例鼻咽慢性炎症患者作对照组测量MEPs。

Results: Scans of 3D-FIESTA sequence combined with post-procession could precisely show labyrinth, nerves and vessels in inner ear and internal auditory canal, as well as the relationship between nerves and vessels around. As to the ability to evaluate nerves in IAC, MPR and VE was superior to MIP; As to the ability to display semicircularesin and cochlea, MIP was the same as double oblique MPR; It was important for VE and oblique sagittal MPR to display the position of foramina nervosa of IAC.

结果：3D-FIESTA序列扫描结合MPR、MIP和VE重组对内耳迷路及内听道内神经及血管显示清晰，能够清晰显示两者之间的关系，MPR和VE重组对神经的显示优于MIP重组，MIP对半规管显示与双斜面MPR并无明显差别，VE和斜矢状面对于内听道内各神经孔的位置关系具有重要意义。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
