概括
负重的腰部MRI显示了与卧卧式成像相比显著的解剖学差异. 这项研究证实了两种位置的腰椎形态的可靠测量.
科学领域:
- 放射学 放射学是一门学科.
- 整形外科 整形外科 整形外科
- 人体解剖学 解剖学 解剖学
背景情况:
- 传统的卧式腰部磁共振成像 (MRI) 可能会错过可通过直立成像检测到的解剖变化.
- 负重力 (WB) 核磁共振有可能揭示在标准仰卧扫描中看不见的微妙脊柱变化.
- 这项研究旨在量化和比较卧底和WBMRI之间的腰椎尺寸.
研究的目的:
- 为了比较腰椎脊柱形态,使用仰卧和承重 (WB) 磁共振成像 (MRI).
- 为了量化卧底和WB腰椎脊椎成像之间的形态差异.
- 评估从两种成像位置获得的测量结果的评分器内可靠性.
主要方法:
- 在一周内,12名健康成年人接受了两次腰椎MRI,在仰卧和腰椎位置.
- 线性,角尺寸和横截面积 (CSAs) 测量了从斜T2加权图像.
- 使用重复测量分析和类内相关性 (ICC) 测试了评价者内部可靠性.
主要成果:
- 测量显示了线性,角形和CSA数据的强烈位置内相关性 (r=0.75-0.97).
- 在仰卧和WB位置之间的所有测量后腰椎尺寸中观察到显著差异 (p<0.05).
- 会议间的测量显示出强烈的相关性 (r=0.64-0.83),ICC证实了高测量一致性.
结论:
- 腰椎的解剖学尺寸在卧底和腰椎之间表现出一致且显著的差异.
- 与卧卧式成像相比,WB MRI提供了不同的形态学数据,用于特定的脊柱参数.
- 获得的测量值对于卧底和WB腰椎评估都是可靠的.

Magnetic Resonance Imaging
5.2K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Anatomical Positions
10.1K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...
