概括
整个耳T2信号的变化与前置性 schwannoma 患者的听力变化随着时间的推移有很弱的相关性. 这种自动化细分方法显示了评估耳信号变化的潜力.
科学领域:
- 神经成像是一种神经成像.
- 听力学 听力学是指听力学.
- 神经外科 神经外科
背景情况:
- 静脉瘤 (VS) 的管理涉及观察,需要可靠的方法来监测听力.
- 在MRI上耳T2信号的变化可能反映了内耳的状态,但它们与VS中的听力相关性尚未确立.
研究的目的:
- 评估通过自动细分评估的整个耳T2信号变化与观察到前庭神经瘤的患者的听力水平之间的相关性.
- 为了确定耳T2信号的变化是否先于或随着时间的推移而导致听力改变.
主要方法:
- 对127名前庭神经瘤患者的回顾性研究,至少两次MRI扫描和听力图.
- 自动细分用于从T2加权MRI序列分析整个耳T2信号比率 (两侧到对侧).
- 与诊断时和随着时间的推移使用纯色调平均 (PTA) 和文字识别得分 (WRS) 的相关性分析.
主要成果:
- 在诊断时的耳T2信号比率和听力水平之间没有发现显著的相关性.
- 随着时间的推移,耳T2信号比率的变化与PTA的变化有很弱的相关性,但不是WRS.
- 耳信号比率的变化跟随,而不是先于PTA和WRS的变化.
结论:
- 整个耳T2信号比率在观察到的前庭神经瘤患者中与听力变化存在微弱的相关性.
- 自动细分技术对未来对导致耳信号变化的条件的评估有希望.

Anatomy of the Ear
8.5K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

The Cochlea
45.3K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

Equilibrium and Balance
4.8K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
