概括
过渡到磁共振成像 (MRI) 对于急性缺血性中风 (AIS) 是可行的. 虽然血栓溶解候选人出现了轻微延迟,但MRI减少了中风模仿和亚急性成像需求,具有类似的诊断和残疾结果.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 脑卒中医学 脑卒中医学
背景情况:
- 对于急性缺血性中风 (AIS) 诊断的最佳神经影像模式仍在争论中,中心正在从计算机断层扫描 (CT) 过渡到磁共振成像 (MRI).
- 这项研究评估了中心从CT转向MRI作为AIS的主要成像工具对诊断准确性和患者结果的影响.
研究的目的:
- 为了比较CT和MRI之间的诊断和残疾结果,作为急性缺血性中风 (AIS) 的第一线成像.
- 为了评估成像利用的变化,诊断的延迟,和患者的结果后,中心的过渡到MRI对AIS.
主要方法:
- 一个回顾性分析比较了连续AIS患者从CT-first期间 (2012年12月至2018年4月) 与MRI-first期间 (2018年5月至2022年8月).
- 评估的结果包括成像模式的使用,诊断延迟,遗漏的AIS诊断,中风模仿者的血栓溶解,中风机制的确定,住院时间和3个月的残疾.
主要成果:
- 在MRI期间,80%的AIS患者使用MRI作为一线成像,第二种急性成像方式的需求略有增加 (2.1%至5%).
- 血栓溶解候选人的门到成像延迟增加了2分钟,而中风模仿者的血栓溶解减少了一半 (8.6%至4.3%).
- 最初错过的AIS诊断,未识别的中风机制,住院时间和3个月的残疾在CT和MRI期间是相似的.
结论:
- 在综合性中风中心,转向MRI作为AIS的第一线成像是可行的,对血栓溶解候选人成像延迟的影响最小.
- 磁力共振成像的使用与对中风模拟的血栓溶解的减少以及对亚急性神经成像的需求降低有关,而不会影响诊断或功能结果.

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...
