背景情况:

骨关节炎 (OA) 是一种退行性关节疾病.
早期检测和风险分层对于有效管理至关重要.
像T1rho和T2映射这样的先进的MRI技术显示出对评估OA的希望.

研究的目的:

为早期OA开发一个风险分层编号图.
使用MRI,特别是T1rho和T2映射,用于OA预测.
为了创建OA-解剖学签名名组图 (OA-ASN).

主要方法:

分析了199名患有正常或早期OA软骨的患者队列.
已经确定了11个OA-ASN的候选预测因子.
使用C指数,AUC,校准图,DCA和CIC来评估性能.

主要成果:

皮下脂肪 (IPFP) 体积,T1rho和T2映射独立地与早期的OA相关.
在培训 (C指数:0.975) 和验证队列 (C指数:0.904) 中,OA-ASN表现出了很好的歧视.
校准图表和决策分析证实了名图的临床实用性.

结论:

较小的IPFP体积,T1ρ>33,T2映射>35.04是OA的重要指标.

Magnetic Resonance Imaging

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...
