概括
磁共振成像 (MRI) 和X射线显示出高度一致性,用于测量形指数 (AI) 和关键肩角 (CSA). 这些成像方法可靠地评估肩部解剖学,MRI被证明是X光片的合适替代品.
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.
- 人体解剖学 解剖学 解剖学
背景情况:
- 肩形指数 (AI) 和关键肩角 (CSA) 是诊断肩部病理的重要解剖测量.
- 比较放射和磁共振成像 (MRI) 的测量对于理解诊断准确性和可靠性至关重要.
研究的目的:
- 为了比较从肩部放射和MRI中获得的AI和CSA的绝对值.
- 评估在两种成像方式中对AI和CSA测量的观察者间和观察者内部协议.
主要方法:
- 来自124名受试者的肩部放射和核磁共振 (MRI) 被两名受过奖学金培训的肩部外科医生分析.
- 对AI和CSA的测量进行了两次,隔12周,以评估观察者内部的可靠性.
- 观测者间和观测者内部的可靠性使用类内相关系数 (ICC) 和布兰德-阿尔特曼图表来量化.
主要成果:
- 在X光照中发现CSA (ICC > 0.93) 和AI (ICC > 0.90) 的高内部观察者一致性.
- 在MRI中对CSA也观察到高的观察者内部一致性 (ICC > 0.94),尽管AI显示出较低的一致性 (ICC = 0.022).
- 对CSA和AI两种模式来说,观察者间的协议是实质性的,ICC值在0.685到0.892.2之间.
结论:
- 放射和MRI都显示出AI和CSA测量的高可靠性.
- AI和CSA的绝对值在两个成像模式之间高度相关.
- 核磁共振是评估AI和CSA的合适和可靠的成像方法,补充了放射性评估.

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...

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,...
