概括
磁共振成像 (MRI) 检测了近三分之一的轮椅使用者脊髓损伤 (SCI) 的深层组织损伤 (DTI). 较长的坐时间和较少的减压是DTI的关键风险因素.
科学领域:
- 生物医学工程 生物医学工程
- 临床医学 临床医学
- 放射学 放射学是一门学科.
背景情况:
- 深层组织损伤 (DTI) 在脊髓损伤 (SCI) 患者中难以诊断,因为缺乏早期皮肤变化.
- DTI起源于皮下组织,并向外进展,这构成了重大的临床挑战.
研究的目的:
- 用MRI评估轮椅依赖的成年人患有SCI的DTI发病率.
- 为了确定该人群中DTI相关的风险因素.
主要方法:
- 一项横截面的观察性研究,涉及56名依赖轮椅的成年SCI患者.
- 盆腔松部STIRMRI查进行了检测DTI.

8.9K
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,...
