- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
- 运动医学 运动医学
背景情况:
- 脚关节的关节软骨体积可能受到与运动有关的压力的影响.
- 磁共振成像 (MRI) 场强度会影响图像质量.
研究的目的:
- 评估运动,非运动和非运动生活方式对脚软骨体积的影响.
- 为了比较1.5 Tesla (T) 和3.0 T MRI扫描仪的图像质量,用于脚关节评估.
主要方法:
- 15名健康受试者 (运动员和非运动员) 使用1.5T和3.0T扫描仪对他们的脚关节进行了MRI扫描.
- 骨和骨的软骨体积是从VIBE序列图像计算出来的.
- 放射科医生使用1-5分数尺度对图像质量进行了定性评估.

5.2K
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,...
