概括
在手术前对关节软骨和骨质量进行T2映射,可以预测关节镜术后患者的结果. 较低的组织质量表明T2值较高,与较低的长期国际关节结果工具 (iHOT-12) 得分相关.
科学领域:
- 整形医学
- 放射学
- 运动医学
背景情况:
- 部撕裂是一种常见的部损伤.
- 评估手术前的组织质量对于预测手术结果至关重要.
- T2映射是一种非侵入性MRI技术,用于评估软骨和骨完整性.
研究的目的:
- 调查手术前T2映射值与患者报告的结局 (iHOT-12) 在关节透视术后的关系.
- 确定T2映射是否可以作为关节保护手术的预后工具.
主要方法:
- 对29名患者 (14- 50岁) 进行关节镜检查,以检查关节裂痕 (修复或重建).
- 腿部,骨和骨组织的手术前MRI T2值被盲目的审查者评估.
- 在手术前和手术后的24个月内收集了国际结论工具 (iHOT-12) 的得分.
- 单变量混合线性模型分析了T2值和iHOT-12得分之间的关联.
主要成果:
- 较高的手术前T2值与较高的iHOT-12得分在基线和早期术后相关 (p < 0. 05).
- 在所有评估结构中,较低的手术前T2值与更好的12个月和24个月iHOT-12得分相关 (p < 0. 001).
- 这些依赖时间的相关性在劳拉修复和重建子组中一致.
结论:
- 在手术前的T2映射显示了与关节镜术后患者报告的结果的时间依赖关系.
- 根据T2值的增加,软骨或部组织质量较差预示着较差的长期功能结果.
- 在关节保护手术中,T2映射是一种有价值的手术前预后工具.

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...
