概括
面部神经在眼和迷宫部分的增强是一个正常的MRI发现后对比T1加权,脂肪和VIBE序列. 这一发现在1.5T和3T扫描仪中是一致的,这表明它不是病理学的迹象.
科学领域:
- 神经辐射学神经辐射学
- 医疗成像医学成像
- 神经科学是一个神经科学.
背景情况:
- 在MRI上面部神经的增强可以归因于其血管.
- 传统上,超出生殖腺节的增强被认为是正常的,而状和迷宫部分被认为是异常的.
研究的目的:
- 调查面部神经的状和迷宫部分的增强是否是一种正常的发现.
- 通过使用1.5T和3T核磁共振扫描仪,对后对比T1加权,脂肪和体积互波呼吸屏蔽检查 (VIBE) 序列进行评估.
主要方法:
- 对50名没有面部神经症状的患者 (100个面部神经) 的回顾性分析,这些患者接受了用内部听觉通道协议进行MRI.
- 两位神经放射学家独立评估了来自1.5T和3T扫描仪的T1加权后对比,脂肪和VIBE序列的面部神经段增强.
主要成果:
- 在1.5T磁力共振成像上,在80%的眼段和92%的迷宫段中观察到增强.
- 在3T磁力共振扫描上,在60%的眼段和84%的迷宫段中观察到增强.

Magnetic Resonance Imaging
5.0K
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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan
105
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT)
274
Insensitive Nuclei Enhanced by Polarization Transfer (INEPT) is an advanced Nuclear Magnetic Resonance (NMR) technique specifically designed to detect and enhance the signals of low-abundance nuclei, such as carbon-13 and nitrogen-15, in small molecules. The fundamental principle behind INEPT is the transfer of polarization from a more abundant and highly polarizable nucleus, typically hydrogen-1, to the low-abundance nucleus of interest. This process effectively boosts the NMR signal of the...

Cranial Nerves: Overview and Anatomy
1.7K
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...

Veins of Head and Neck
1.6K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...
