概括
在精神病学中,常规的大脑MRI在37%的患者中发现了可行的发现,支持在特定情况下使用它. 建议精神病患者使用包括DWI,SWI,FLAIR和3D T1在内的最小成像协议.
科学领域:
- 神经成像是一种神经成像.
- 精神病学是一个精神病学.
- 放射学 放射学是一门学科.
背景情况:
- 在精神病学实践中,常规脑部MRI的临床价值仍然是有争议的,因为各种协议.
- 在精神病患者中,命令和解释大脑MRI的做法是不一致的.
研究的目的:
- 评估用于精神病患者的局部大脑MRI协议.
- 确定这些脑MRI的临床相关性和发现的产量.
主要方法:
- 一个单一中心的回顾性研究分析了精神病学家从2017年10月到2024年6月要求的大脑MRI.
- 图像检测协议进行了审查,结果被分类为可起诉 (AF+) 或不可起诉 (AF-).
- 可采取行动的发现进一步按紧迫性进行分类:即时,紧急或例行.
主要成果:
- 在532名患者中,有37%的患者有可行的发现 (AF+),大多数患者需要例行管理.
- 通常使用的协议包括DWI,SWI,FLAIR和3D T1序列.
- AF+检测因序列而异 (FLAIR:72%,3D T1:60%),特定的病变仅在专用序列上可见 (例如,DWI用于缺血症,SWI用于微型血液).
- 随着年龄的增长,AF+的可能性会增加,并且与精神病 (28.8%) 或抑郁症 (45.5%) 相比,神经认知症状 (84.9%) 的患者更高.
结论:
- 大脑MRI在大约三分之一的精神病患者中发现了可行的发现.
- 一个最小的协议 (FLAIR,3D T1,DWI,SWI) 支持大脑MRI在选定的精神病患者群体中的临床相关性.
- 这些发现提倡在精神病学中明智地使用脑部MRI,以适当的成像协议为指导.

Magnetic Resonance Imaging
9.1K
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...
