概括
宫脊髓的定量核磁共振 (qMRI) 显示了肌缩侧面硬化症 (ALS) 患者和健康对照人群之间的显著差异. 这些发现凸显了qMRI的重要意义.
科学领域:
- 神经成像是一种神经成像.
- 生物标志物发现发现
- 神经学 神经学
背景情况:
- 肌缩侧面硬化症 (ALS) 在疾病跟踪和预后方面存在挑战,原因是复杂的中枢神经系统病理学.
- 定量MRI (qMRI) 为评估ALS中脊髓变化提供了潜在的生物标志物.
研究的目的:
- 系统地审查和分析ALS患者椎脊髓的定量MRI (qMRI) 生物标志物变化.
- 评估qMRI指标在ALS患者和健康对照人群之间的歧视潜力.
主要方法:
- 在PubMed,Scopus,Cochrane图书馆和Web of Science数据库中进行系统的文献搜索,直到2023年8月.
- 包括报告宫脊髓qMRI参数 (DTI,MTR,CSA等) 的研究. 在ALS和对照组中.
- 使用标准化平均差异 (SMD) 和聚合规范值的元分析;研究质量通过纽卡斯尔-太华尺度 (NOS) 进行评估.
主要成果:
- 包括30项研究 (1817名参与者),大多数被认为是高质量的.
- 与对照组相比,在ALS患者中观察到宫脊髓横截面积 (CSA) 和小分异型 (FA) 的显著减少,以及平均扩散率 (MD) 的增加.
- 在宫扩大 (C4-C6) 中观察到选择性缩,在左侧皮质脊柱管中特别减少了FA.
结论:
- 宫脊髓qMRI指标显示,在区分ALS与健康个体方面,有很大的潜力.
- 在C4-C6区域观察到的选择性缩是一个可重现的发现,也是一个潜在的成像标志物,用于量化ALS下部运动神经元退化.

01:16Spinal Cord: Cross-sectional Anatomy
2.4K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

01:54The Spinal Cord
29.7K
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
