概括
在没有脑损伤的脑 (CP) 中,遗传原因更频繁. 对于所有CP病例,建议进行基因组测试,因为神经成像本身不应该排除遗传诊断.
科学领域:
- 遗传学 遗传学 是一个
- 神经科学是一个神经科学.
- 儿科 儿科 儿科
背景情况:
- 大脑 (CP) 影响80-86%的神经成像异常的个体.
- 损伤性白质 (WMI) 或灰质损伤 (GMI) 在CP中很常见,通常归因于环境因素.
- 非损伤性CP和正常神经成像的遗传原因是假设的,但这需要验证.
研究的目的:
- 评估遗传病因在非损伤性脑 (CP) 中更为普遍的假设.
- 为了确定基因组测试在CP的不同神经成像分类中的诊断产量.
- 评估神经成像在指导CP遗传测试决策中的作用.
主要方法:
- 来自澳大利亚CP生物库的331名患有CP的儿童 (1986年至2018年出生) 的基于人口的研究.
- 基因组DNA测序,变异过和使用ACMG-AMP标准进行分类.
- 神经成像 (MRI,CT,超声波) 编码使用磁共振成像分类系统 (MRICS).
主要成果:
- 在24%患有CP的儿童中,发现了遗传病因.
- 与WMI (19%) 或GMI (10%) 的儿童相比,患有发育不良 (41%),各种发现 (48%) 和正常神经影像 (39%) 的儿童的遗传诊断更频繁.
- 相对风险比率表明,与损伤相比,非损伤性CP类别的遗传分辨率显著更高.
结论:
- 研究结果支持这样一个假设:在非损伤性CP中,遗传原因更为常见.
- 在所有神经成像类别中确定了遗传诊断,包括17%的损伤性脑损伤.
- 神经成像应该指导,而不是排除,在脑评估的基因组测试.

Imaging Studies IV: Magnetic Resonance Imaging
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,...
