概括

大脑MRI异常常见于急性松性脑膜炎 (AFM),通常影响pons. 这些变化通常会随着时间的推移而消失,支持AFM诊断,即使是脑成像发现.

科学领域:

神经学神经学
神经辐射学神经辐射学
传染性疾病传染性疾病

背景情况:

急性软性脑膜炎 (AFM) 的特征是MRI上出现急性软性和脊髓灰质干扰.
在AFM中报告了脑MRI异常,但需要进一步描述.
了解这些大脑变化对于准确的AFM诊断和管理至关重要.

研究的目的:

评估AFM中脑MRI异常的急性特征. 在AFM中评估脑MRI异常的急性特征.
为了评估AFM患者大脑MRI发现的演变.

Magnetic Resonance Imaging

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...
