概括
形态学磁共振成像 (MRI) 后处理识别了第一次发作和正常MRI扫描患者的微妙病变. 这种先进的MRI技术有助于诊断,并预测更高的发作复发率.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 的研究研究.
背景情况:
- 标准的MRI通常无法检测第一次发作患者的微妙发病性病变.
- 早期和准确的诊断对于治疗和预防进一步的发作至关重要.
研究的目的:
- 评估在患有第一次发作和初始MRI阴性患者中微妙病变的形态核磁共振成像后处理的诊断益处.
- 为了将这些发现与临床数据,发作复发和诊断相关联.
主要方法:
- 追溯对97个MRI扫描的回顾,这些MRI扫描来自于患有第一个未引起的发作且在常规MRI上没有可见的病变的患者.
- 利用形态分析程序 (MAP) 软件用于自动后处理3D T1加权的MRI数据以检测微妙的病变.
- 与传统MRI一起对MAP概率图进行盲目审查,与临床和脑电图数据相关联.
主要成果:
- 形态测量分析计划 (MAP) 在最初MRI阴性患者中的18.6%中发现了暗示着焦点皮质发育不良的微妙皮质变化.
- 与MAP阴性患者 (27.8%在1年,34.2%在2年) 相比,MAP阳性患者 (MAP+) 的发作复发率 (61.1%在1年,66.7%在2年) 显著更高.
- 在MAP+患者中,被诊断为的可能性要大得多 (OR=21.371,p<.001).
结论:
- 形态核磁共振扫描 (MRI) 后处理是检测常规核磁共振 (MRI) 错过的微妙发性病变的宝贵工具,用于首次发作患者.
- 首次发作患者的积极MAP发现与高发作复发率相关,表明的发作.
- 这种先进的成像技术有助于早期诊断和治疗.

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...
