概括
不增强的T2加权成像 (T2WI) 准确评估脑膜瘤尺寸和生长,与增强对比度的MRI相比. 这简化了监控,降低了成本和加多暴露风险.
科学领域:
- 神经辐射学神经辐射学
- 在瘤学瘤学.
- 医疗成像医学成像
背景情况:
- 脑膜瘤需要定期的MRI监测来监测瘤.
- 与对比度增强的MRI (CE-T1WI) 是标准的,但涉及成本,风险和加多积累问题.
研究的目的:
- 评估单独用于评估脑膜瘤特征的轴向T2加权成像 (T2WI) 的准确性和可靠性.
- 将仅T2WI的评估与使用CE-T1WI和T2WI的现行实践进行比较.
主要方法:
- 追溯分析136名患有脑膜瘤的成年患者和两次MRI扫描 (间隔≥6个月).
- 盲人神经放射学家对CE-T1WI和T2WI序列的独立评估.
- 评估瘤尺寸,生长和静脉入侵,使用科恩的卡帕和类内相关系数 (ICC).
主要成果:
- 单独T2WI显示出与CE-T1WI和T2WI组合用于检测瘤生长的近乎完美的一致性 (κ = 0.945).
- 在单独使用T2WI进行生长检测时,高精度 (97.8%),特异性 (100%) 和灵敏度 (92.3%).
- 对静脉入侵和瘤尺寸的良好至优秀的interrater/intrarater可靠性达成实质性协议 (κ = 0.771).
结论:
- 未增强的T2WI是评估脑膜瘤尺寸,生长和静脉入侵的可靠和准确的替代方案.
- 仅T2WI提供了与对比增强协议相匹配的有效性,可能减少资源利用和风险.

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...
