概括

带有可旋转磁铁的耳植入物 (CI) 通常在MRI期间显示出良好的安全性,尽管工件可能会影响图像质量. 当按照指南使用时,Med-El Synchrony模型似乎存在较少的安全问题.

科学领域:

耳鼻喉科耳鼻喉科耳鼻喉科
放射学放射学是一门学科.
生物医学工程生物医学工程

背景情况:

耳植入物 (CI) 对于恢复听力至关重要.
磁共振成像 (MRI) 是一种至关重要的诊断工具.
CI磁铁和MRI磁场之间的相互作用带来了安全和文物挑战.

研究的目的:

在MRI扫描过程中,审查当前的带有可自由旋转磁铁的耳植入器的特性,安全性和工件.
评估特定CI模型的MRI兼容性的临床数据.

主要方法:

对PubMed,Cochrane和Web of Science数据库进行系统审查.
使用"磁共振成像"等术语以及特定的CI模型和磁铁类型进行搜索.
不包括非人类,非英语和尸体研究;使用MMAT和GRADE评估质量.

主要成果:

审查了18项研究;在两个CI模型中,在3个病例中报告了疼痛并发症.
没有发生去磁化;只注意到一个磁位移.
磁力共振成像器件很常见,但通常被允许,但仅限于良好的诊断可用性;很少需要扩展.

Magnetic Resonance Imaging

7.3K

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,...
