- 发育儿科 发育儿科
- 新生儿科学 新生儿科学
背景情况:
- 新生儿大脑磁共振成像 (MRI) 对于检测大脑损伤和预测高危婴儿的结果至关重要.
- 当前的临床实践往往会将MRI推迟到术语等效年龄 (TEA),这需要对早产婴儿的家属进行重复的医院访问.
- 早期预测神经发育结果,如脑 (CP),对于及时干预至关重要.
研究的目的:
- 为了评估2年神经发育结果的早期新生儿和期同等年龄 (TEA) 的MRI中结构性大脑生物标志物的预测准确性.
- 为了确定早期MRI,TEA MRI,或两者的组合是否能更好地预测结果.
- 确定与早期儿童神经发育评估相关的特定大脑结构生物标志物.
主要方法:
- 从PPREMO和PREBO研究中的100名非常早产婴儿的大脑MRI中提取了结构生物标志物.
- 核磁共振成像在新生儿时期 (从月经后26周开始) 和TEA时获得.
- 使用多变量回归来评估MRI生物标志物与2年结果 (贝利-III和NSMDA) 之间的关联.
主要成果:
- 在早期和TEAMRI和2年后的结果中,在大脑结构之间发现了中等强度和统计学上显著的关联 (r = 0.37-0.56).
- 关键的预测生物标志物包括白质和灰质体积,深灰质和小脑体积,皮质旋转和表面积.
- 早期MRI显示出最高的预后准确性,与结合早期和TEA时间点相当.

Magnetic Resonance Imaging
7.6K
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,...
