Magnetic Resonance Imaging

5.1K
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...

科学领域:

  • 放射学 放射学是一门学科.
  • 手术瘤学手术瘤学
  • 医疗器械 医疗器械

背景情况:

  • 与MRI兼容的无线SCOUT定位系统于2022年4月被FDA批准.
  • 磁力共振成像指导的定位对于精确的手术准磁力共振成像检测到的异常至关重要.

研究的目的:

  • 为了评估MRI引导SCOUT定位的可行性.
  • 为了比较MRI引导SCOUT定位与传统MRI引导线路定位的结果.

主要方法:

  • 在2022年10月至2023年7月期间,对接受MRI引导SCOUT或线路定位的患者的电子病历和成像的回顾性审查.
  • 统计分析使用2样本比例和威尔科克森等级总和测试来比较并发症率和手术的时间.

主要成果:

  • 分析了14个MRI引导的SCOUT和23个MRI引导的电线定位病例.
  • 所有的SCOUT安置都很简单,位置也很好.
  • 在SCOUT和线路定位之间,没有观察到SCOUT和线路定位之间的并发症率或检测到手术的时间有显著差异.

结论:

  • 以MRI指导的SCOUT定位是一种可行的替代电线定位,没有报告的并发症.
  • 虽然在活检期间放置SCOUT可以消除额外的手术,但预测其适合随后的乳腺保护手术需要进一步调查,因为在活检时放置的60%没有用于手术.
