概括
通过将临床评估与脑损伤程度的磁共振扩散权重成像 (MR DWI) 结合起来,可以改善早期中风预后. 这有助于预测患者在入院后不久的康复结果.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 准确的早期预后对于最佳的中风患者管理至关重要.
- 通过MR DWI评估缺血性脑损伤的程度可能会提供超出临床因素的额外预后价值.
研究的目的:
- 评估MR扩散权重成像 (DWI) 程度是否为中风恢复提供预后信息.
- 利用临床和成像数据开发一个良好的中风恢复预测模型.
主要方法:
- 这项三阶段研究涉及66名来自北美和63名来自澳大利亚的患者.
- 收集的数据包括中风开始后36小时内MR DWI,NIH中风量表 (NIHSS) 评分和3个月后的Barthel指数.
- 后勤回归被用来构建和验证预测模型,导致一个三项恢复预测尺度.
主要成果:
- 综合NIHSS得分,MR DWI的时间和MR DWI上的缺血组织体积最好预测中风恢复 (p<0.05).
- 该模型表现出强大的外部验证,具有0.77的灵敏度和0.88的特异性.
- 一个三项尺度确定了中风恢复的低,中,高概率.
结论:
- 将临床因素与MR DWI发现相结合,与单独使用单个因素相比,可以提高中风恢复预测.
- 为预测中风恢复的早期临床使用,开发了一种实际的三项尺度.

01:19Three-Winding Transformers
Three identical single-phase transformers can be configured to form a three-phase transformer connection, which involves high-voltage and low-voltage windings. The high-voltage windings are denoted by capital letters A-B-C, while the low-voltage windings are labeled with lowercase letters a-b-c, representing their respective phases. This notation helps distinguish between the high and low voltage sides of the transformer.

01:28Meridians
In surveying, meridians are vital reference lines to measure directions and establish accurate land orientations. Meridians run from the north to the south poles, providing a stable framework for angular measurements and mapping. Meridians are fundamental in survey design, with the primary types being astronomic, magnetic, and assumed meridians. Each type offers distinct benefits and limitations, selected based on the project's scale and precision needs.The astronomic meridian is aligned with...
