概括
由于大脑的广泛异常,婴儿 (IS) 会导致严重的神经发育问题. 早期神经成像可以识别这些结构缺陷, 以指导受影响儿童的干预.
科学领域:
- 神经科学
- 儿童发育医学
- 放射学
背景情况:
- 婴儿是一种严重的综合征,伴有严重的神经发育障碍.
- 在IS中潜在的大脑微观结构和功能变化仍然不完全理解.
- 先进的神经成像对于阐明神经功能障碍的解剖相关性至关重要.
研究的目的:
- 研究婴儿 (IS) 患者的灰色和白质异常.
- 这些结构性大脑变化与神经功能障碍相关联.
- 使用先进的神经成像技术进行全面分析.
主要方法:
- 磁共振成像 (MRI) 包括基于声素的形态测量 (VBM),基于表面的形态测量 (SBM) 和扩散张力成像 (DTI).
- 在34名IS患者和32名健康对照患者的灰质体积 (GMV),皮质厚度和白质完整性的分析.
- 使用贝利婴儿发育尺度-II评估认知和运动功能.
主要成果:
- 与HC患者相比,IS患者的精神发育指数 (MDI) 和身体发育指数显著下降.
- 在包括部,部和边缘区域在内的各种大脑区域观察到减少的GMV和皮质稀薄.
- 在皮质脊髓和海马环膜通道中发现白质完整性下降,左中回形的GMV与MDI得分相关.
结论:
- 婴儿与广泛的微观结构性脑部异常有关,影响视觉,听觉语言,运动和边缘功能至关重要的区域.
- 结构性缺陷,特别是皮和皮,可能是IS中观察到的神经发育障碍的基础.
- 早期神经成像对于识别功能障碍的解剖相关性和提供有针对性的治疗干预至关重要.

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...

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,...
