概括
额外的头骨核磁共振扫描对于先前阴性CT扫描的非创伤性头痛患者有价值,特别是那些早期再访,全身症状或症状变化的患者. 这有助于指导患者管理和识别严重疾病.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 紧急医疗 紧急医疗
背景情况:
- 非创伤性头痛是急诊室访问的常见原因之一.
- 头部计算机断层扫描 (CT) 通常是最初的成像模式.
- 在头部CT检测呈阴性后,额外的头骨磁共振成像 (cMRI) 的实用性需要进一步调查.
研究的目的:
- 评估cMRI在患有非创伤性头痛的患者中诊断产量和临床影响,这些患者最近有一个负面的头部CT.
- 分析影响cMRI诊断产量的因素,包括再访时间,护理环境和临床表现.
主要方法:
- 追溯分析了162名患有非创伤性头痛的成年患者,他们在阴性头部CT后的一个月内接受了cMRI.
- 对诊断产量,错误转诊率和患者管理变化 (PMC) 的分析.
- 数据的分层是根据再访持续时间 (早期与晚期) 和护理环境 (急诊部与门诊) 的分层.
主要成果:
- 整体cMRI诊断收益率为17.3%,误诊率为1.2%.
- 与门诊诊所 (9.1%) 相比,急诊部的诊断收益率明显高 (24.7%).
- 在早期复诊患者 (25.4%) 中观察到的最高收益率,特别是那些有全身症状 (45%) 或症状变化 (46.7%) 的患者.
- 积极的cMRI发现导致90%的病例患者管理变化,主要是入院和治疗.
结论:
- cMRI显示,在以前阴性CT的非创伤性头痛患者中,显著的诊断收益率是显著的,特别是在ED环境中的早期复查中.
- 系统性体征和症状变化是考虑cMRI的关键指标.
- 在门诊设置中,负的cMRI可能有助于确认头痛的良性性质,从而可能避免进一步的干预.

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...
