概括
使用特定序列的磁共振成像 (MRI) 可以识别创伤性下部神经损伤. 增加的信号与噪声比率 (FSNR) 和神经肌肉对比与噪声比率 (FNMCNR) 是神经损伤的关键指标.
科学领域:
- 医疗成像医学成像
- 神经学 神经学
- 在口腔外科手术.
背景情况:
- 由于口腔手术造成的性下神经损伤,由于缺乏客观方法,因此存在诊断挑战.
- 这种模糊性使治疗,赔偿变得复杂,并经常导致医疗法律纠纷.
研究的目的:
- 使用特定的MRI协议识别创伤下神经损伤的歧视因素.
- 建立对外围三神经损伤的客观诊断标准.
主要方法:
- 26名下神经受伤的患者接受了专门的MRI测序 (T2 Flex,3D STIR,DWI与PROPELLER).
- 损伤的神经与相反的健康神经进行了比较,评估了FSNR,FNMCNR,SSNR,SNMCNR,ADC和横截面神经区域等参数.
主要成果:
- 该研究发现,增加的FSNR和FNMCNR是创伤性下部神经损伤 (p <0.05) 的显著歧视因素.
- 诊断性能显示FSNR的AUC为0.712,FNMCNR的AUC为0.7056,这表明准确度很好.
结论:
- 在应用的MRI序列中增加的FSNR和FNMCNR是创伤性神经损伤的准确指标.
- 这项研究为开发先进模型的基础,用于在较大的患者群体中诊断三角神经创伤.

Magnetic Resonance Imaging
5.1K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...
