概括
股骨头脱中心 (FHD) 在有症状的部更常见,并与部不稳定性和形有关. 放射性MRI是检测FHD的最佳成像方法,这种方法在无症状个体中很少见.
科学领域:
- 整形外科成像 整形外科成像
- 部的生物力学
- 放射学 放射学是一门学科.
背景情况:
- 骨头脱中心 (FHD) 是部不稳定的潜在指标.
- 了解不同成像平面的FHD流行情况及其与部形态的关联对于诊断至关重要.
研究的目的:
- 为了比较FHD在症状与无症状部的各种MRI成像平面上的患病率.
- 为了调查FHD与骨变形,关节损伤和对比剂使用之间的关联.
主要方法:
- 对症状患者的3T部MRI关节学 (MRA) 和无症状对照中的非对照MRI的回顾性分析.
- 对轴向,斜面和辐射图像的FHD评估,定义为白和大腿骨头之间的流体层.
- 后勤回归用于评估与形,关节损伤和对比类型的关联.
主要成果:
- 与无症状对照组 (2%) 相比,FHD在有症状的部 (30%) 中明显更为普遍,特别是在辐射图像上.
- FHD的患病率与关节内或静脉内使用对比剂无关.
- FHD与部发育不良,过度的股骨扭曲和严重的软骨损伤有很强的相关性.
结论:
- 放射性MRI是确定FHD的最佳方式.
- 在有症状的部中,FHD与潜在的骨变形有关,这些变形会导致不稳定.
- FHD可以作为部不稳定的标志物,帮助手术决策.

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...
