概括
这项研究表明,专门的MRI扫描可用于评估末期肝病 (ESLD) 患者的肌肉组成. 它可以识别肌骨病,与这些患者的身体功能较差有关.
科学领域:
- 肝病学和胃肠道学
- 放射学和成像学 放射学和成像学
- 老年病学和老年学.
背景情况:
- 末期肝脏疾病 (ESLD) 中,肉症和骨髓炎是常见的,影响患者的治疗结果.
- 在ESLD中肌肉组成,脆弱性和肉症之间的关系需要进一步调查.
- 需要新的成像技术来准确评估ESLD患者的肌肉质量.
研究的目的:
- 评估专门的MRI协议 (AMRA® MAsS Scan) 的可行性,以评估ESLD患者的肌肉组成.
- 为了确定大腿肌肉的组成是否与验证的脆弱性和肉类的测量相关.
- 探索肌肉骨病在ESLD患者群体中的临床影响.
主要方法:
- 一项前性,单中心研究招募了患有ESLD的成年肝移植候选人.
- 使用AMRA® MAsS扫描来评估大腿肌肉的组成.
- 分析了与脆弱性和肉眼的相关性,包括6分钟步行测试.
主要成果:
- 在18名ESLD患者中,17名 (94%) 的MRI方案是可行的,平均完成时间为14.9分钟.
- 41%的患者表现出不良的肌肉组成 (高脂肪透,低肌肉体积).
- 不良的肌肉构成与最近的大体积体和在6分钟步行测试中的表现明显差.
结论:
- AMRA® MAsS扫描是一种可行的工具,用于量化ESLD患者的骨髓炎.
- 骨髓炎在ESLD中很普遍,可以作为肌肉质量和功能的标志物.
- 这种MRI技术有可能改善ESLD肌肉相关并发症的评估和管理.

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...
