概括
脊髓梗塞 (SCI) 是一种罕见的骨髓病变,经常被误诊为横向骨髓炎 (ITM). 独特的临床和MRI特征,包括较短的开始至nadir时间和特定的病变模式,有助于区分SCI与ITM.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 骨髓病学研究 骨髓病学研究
背景情况:
- 脊髓梗塞 (SCI) 是一种罕见但严重的骨髓病变,预后不佳.
- SCI经常被误诊为异常性横侧髓炎 (ITM).
- 准确的区分对于适当的患者管理至关重要.
研究的目的:
- 确定SCI的临床特征.
- 为了确定SCI诊断的放射性生物标志物.
- 根据临床和成像发现,区分SCI和ITM.
主要方法:
- 追溯观察队列研究 (2019年1月 - 2024年10月).
- 包括诊断为SCI和ITM的患者.
- 分析临床数据,放射学发现 (包括DWI,ADC,T2加权MRI) 和功能结果.
- 单变量分析用于群体差异化.
主要成果:
- 确定了22名SCI患者,12名通过DWI/ADC确认.
- SCI发作至nadir的时间明显比ITM短 (大多在6小时内).
- 脊髓损伤显示出线性斜腰MRI病变; ITM呈现为斑块状/状病变.
- 在T2加权的MRI上发现了一种新的"古怪标志",用于SCI.
- 脊髓损伤患者通常经历更差的预后和更高的依赖性.
结论:
- 临床特征和特定的放射性迹象可以诊断SCI.
- 包括病变形态和"古怪的标志"在内的MRI生物标志物区分SCI和ITM.

Spinal Cord
1.7K
The spinal cord, a critical component of the central nervous system, extends from the base of the brainstem to the lumbar region of the vertebral column. It is essential for maintaining physical stability and facilitating communication between the brain and peripheral parts of the body.

The Spinal Cord
31.7K
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.

Spinal Cord: Information Processing
3.4K
The spinal cord is an integral hub for motor and sensory information that enables the brain to communicate with the peripheral nervous system (PNS). This communication consists of relaying sensory data and transmission of motor commands.
Sensory Information Processing
Sensory information processing begins at the sensory receptors located in the skin and other tissues, which detect somatic sensory stimuli such as touch, temperature, or pain. These receptors function as catalysts, initiating...

Spinal Cord: Gross Anatomy
5.6K
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...

Spinal Cord: Cross-sectional Anatomy
4.6K
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.

Local Anesthetics: Clinical Application as Spinal Anesthesia
1.4K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
