概括
周节性MRI异常 (PMA) 在上下节-间节连续 (IIC) 和状态 (SE) 中一样常见. 潜伏集群分析揭示了与PMA相关的独特的IIC模式,表明了潜在的重叠并为诊断策略提供了信息.
科学领域:
- 神经学 神经学
- 神经成像是一种神经成像.
- 发病学 (Epileptology) 是一个专业的学科.
背景情况:
- 状态 (SE) 是最严重的发作表现,包括性SE和非性SE (NCSE).
- 阴道间阴道连续体 (IIC) 是一种电脑图形,具有周期性放电 (PD),尖峰和波浪 (SW) 或横向的节律三角形活动 (LRDA).
- 周期性磁共振成像 (MRI) 异常 (PMA) 可能作为ictal活动的生物标志物,但它们与IIC的关系尚未确立.
研究的目的:
- 调查诊断SE和IIC的患者中PMA的发生率.
- 使用潜伏集群分析 (LCA) 探索特定的IIC模式和PMA之间的关联.
主要方法:
- 一项前性队列研究,涉及223名SE或IIC的成年患者.
- 脑电图 (EEG) 和MRI是在诊断后48小时内进行的.
- 在PMA评估中使用了扩散权重成像,液体减弱反转恢复和动脉旋转标记序列;LCA根据病因和EEG特征确定了患者群.
主要成果:
- 在IIC (47%) 和SE (43%) 组中,PMA的发生频率相似.
- 在IIC组中,周周输血是最常见的低频PD/SW (63%),其次是LRDA (31%) 和高频PD/SW (24%).
- LCA确定了两类:第1类 (非单边,高频PD/SW,触发物) 显示PMA较少 (18%),而第2类 (单边,低频PD/SW,各种病因) 显示PMA较多 (50%;OR=5.79,p=0.02).
结论:
- 在IIC和SE中PMA的类似发生表明了这些条件之间的潜在重叠,这引发了关于IIC患者是否可能有未诊断的NCSE的问题.
- 在IIC中以病因为导向的EEG解释方法可以提高诊断准确性.
- 这些发现可以指导IIC和SE患者的增强治疗策略.

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

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...

01:05Atomic Nuclei: Magnetic Resonance
1.2K
The number of nuclear spins aligned in the lower energy state is slightly greater than those in the higher energy state. In the presence of an external magnetic field, as the spins precess at the Larmor frequency, the excess population results in a net magnetization oriented along the z axis. When a pulse or a short burst of radio waves at the Larmor frequency is applied along the x axis, the coupling of frequencies causes resonance and flips the nuclear spins of the excess population from the...

6.9K
Nuclear magnetic resonance (NMR) is a phenomenon exhibited by certain nuclei that can absorb characteristic radio frequency radiation under certain conditions. NMR has been extensively applied in molecular spectroscopy and medical diagnostic imaging. In both these applications, the molecule or subject under study is placed in a magnetic field and irradiated with radio frequency energy.

1.6K
James Marcia's identity status model provides a framework for understanding how adolescents navigate identity formation through varying degrees of exploration and commitment. Marcia's model builds on Erik Erikson's theories of psychosocial development, focusing specifically on how adolescents reconcile individual aspirations with societal expectations. His model describes identity formation as a dynamic process where adolescents move between different states depending on their level...
