概括
儿童大脑MRI的全身麻醉 (GA) 与以儿童为中心的护理 (CCC) 方法相比,产生了更好的图像质量. 然而,CCC图像大多在临床上是可以接受的,这表明GA对儿科MRI的可行替代方案.
科学领域:
- 医学成像医学成像
- 儿科放射学 儿科放射学
- 神经成像是一种神经成像.
背景情况:
- 磁共振成像 (MRI) 对于儿童大脑状况评估至关重要,因为它具有出色的软组织对比度和无电离辐射.
- 儿科MRI通常需要全身麻醉 (GA),以尽量减少运动器件,增加等待时间和成本.
- 儿童为中心的护理 (CCC) 方法旨在减少GA依赖,但其对图像质量的影响需要科学评估.
研究的目的:
- 科学评估以儿童为中心的护理 (CCC) 方法对儿科大脑MRI图像质量的影响,与在全身麻醉 (GA) 下进行的MRI相比.
- 用结构化视觉分级分析 (VGA) 来比较儿童大脑MRI的图像质量,使用GA和没有GA进行.
主要方法:
- 对3-6岁儿童进行脑部MRI的回顾性队列研究.脑部MRI.
- 图像质量使用视觉分级分析 (VGA) 对T2加权的MRI进行评估,由三个独立观察员进行评估.
- 统计分析采用曼-惠特尼U测试;使用科恩和弗莱斯的卡帕测试评估观察者一致性.
主要成果:
- 接受GA的MRI儿童 (n=22) 的图像质量得分明显高 (VGA平均4.32),高于CCC组的儿童 (n=48,VGA平均3.71).
- 观察者内部的可靠性从实质到完美 (κw = 0.64-0.84),而观察者之间的协议是公平的 (κ = 0.32).
- 在GA组中,切片厚度略微较薄 (p < 0.001).
结论:
- 在GA下小儿大脑MRI显示T2加权图像质量优于CCC方法.
- 尽管得分较低,但大多数CCC图像在临床上是可以接受的,支持其作为一种以患者为中心的替代方案来减少GA使用,风险和成本的可行性.
- 视觉分级分析 (VGA) 提供了一种结构化的方法来评估儿科大脑MRI质量,可能有助于标准化标准.

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Weighted Mean
6.5K
While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...

The Sense of Self: Reflected Self-Appraisal and Social Comparison
56.2K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Atomic Weight
14.1K
Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams. Scientists arbitrarily define this amount of mass as one atomic mass unit (amu) or one Dalton. Electrons are much smaller in mass than protons, weighing only 9.11 × 10-28 grams, or about 1/1800 of an atomic mass unit. As a result, they do not contribute much to an element's overall atomic mass. This means that, when considering atomic mass, it is customary to ignore the mass of any electrons and...

Mass and Weight
15.4K
Mass and weight are often used interchangeably in everyday conversation. For example, medical records often show our weight in kilograms, but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of the Earth on an object. It depends on the distance from the center of the Earth. Weight dramatically varies if we leave the Earth's surface, unlike mass, which does not vary with location. On the Moon, for example, the...
