概括
磁共振成像 (MRI) 很少在没有软骨损伤的情况下确定腰骨关节炎 (TFOA). 在大膝关节关节炎 (OA) 队列中,MRI定义的TFOA几乎总是表明软骨病变,这表明软骨参与是OA特征的关键.
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.
- 类风湿病学 类风湿病学
背景情况:
- 磁共振成像 (MRI) 对于早期检测膝关节关节炎 (OA) 的多组织变化至关重要.
- 一个来自Delphi的MRI定义整合了多个关节组织的发现,以分类骨骨关节炎 (TFOA).
- 这种定义可以识别OA即使没有软骨损伤,促使进一步调查.
研究的目的:
- 为了确定MRI定义的TFOA在没有软骨参与的情况下发生的频率,在两个大型美国队列中.
- 评估软骨损伤的一致性作为多组织MRI基于TFOA分类的特征.
主要方法:
- 来自骨关节炎倡议 (OAI) 和多中心骨关节炎研究 (MOST) 队列的参与者基线数据的分析.
- 膝关节的得分使用MOAKS (OAI) 和WORMS (MOST) 的MRI得分系统进行得分.
- 通过使用Delphi标准识别了MRI定义的TFOA,随后对缺少软骨病变和骨质细胞进行了评估.
主要成果:
- 在OAI参与者的17.5%和MOST参与者的32.1% (KL等级<2) 中观察到MRI定义的TFOA.
- 满足TFOA标准但没有软骨病变的膝盖很少见 (0.4%在OAI,1.5%在MOST).
- 在TFOA定义的膝盖中,缺少骨细胞比缺少软骨病变更为常见.
结论:
- 在高危人群中,当膝盖符合多组织TFOA标准时,MRI检测到的软骨损伤几乎总是存在.
- 软骨的参与似乎是用MRI来表征膝关节OA的一个一致的特征.
- 德尔菲定义很少在没有软骨参与的情况下识别OA.

Magnetic Resonance Imaging
9.0K
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...

Knee Joint
3.1K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Imaging Studies for Cardiovascular System IV: CMRI
311
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
