概括

引力磁共振成像 (MRI) 改善了肘部关节空间宽度和软骨可见性,适用于所有年龄段. 最佳引重量因年龄组而异,年轻人受益于较轻的重量.

科学领域:

整形外科整形外科整形外科
放射学放射学是一门学科.
生物医学工程生物医学工程

背景情况:

肘部的拉力MRI增强了放射性头骨 (RC) 关节空间宽度和软骨可视化.
之前的研究没有评估轴向拉动对肘部MRI的年龄特异性影响.

研究的目的:

为了研究轴向拉力对肘部关节空间宽度和软骨可见性的不同年龄组轴向拉力的影响.
为了确定引的有效性是否随着年龄的增长而下降.

主要方法:

30名健康的志愿者 (20岁,30岁,40岁) 接受了肘部MRI,轴引力变化 (0,3,5,7公斤).
关节空间宽度 (JW) 和关节软骨可见度在RC和腰关节进行测量.
此外,还评估了手术内疼痛和不适.

主要成果:

老年人群的关节空间较窄,没有引力.
在所有年龄组中,轴引力始终增加了RC关节空间宽度和改善了软骨可见性.
在腰关节没有发现任何显著的变化;然而,随着引重的增加,疼痛增加.

结论:

轴拉力有效地改善了跨年龄组的肘部关节可视化.
3公斤的引力适用于20至30岁的个人.
对于40多岁的人来说,可以考虑7公斤的引力.

Magnetic Resonance Imaging

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...
