Stroke:六分钟核磁共振成像可用于评价急性缺血性卒中

2014-06-19 睿医编译 睿医资讯

背景及目的:对于急性缺血性卒中患者的评价,核磁共振成像(MRI)与计算机断层扫描相比,仍需要进一步提高采集速度。方法:此项前瞻、单中心研究的入选标准为急性缺血性卒中发作24h表现出临床症状的患者。美国国立卫生研究院卒中量表≥3,无MRI禁忌症。回波平面成像(EPI)结合平行采集技术用于3T磁共振(MR)扫描以加速收集速度。2位神经系放射专家独立分析图像。结果:62位患者符合入选标准,22位患者接受

背景及目的:对于急性缺血性卒中患者的评价,核磁共振成像(MRI)与计算机断层扫描相比,仍需要进一步提高采集速度。

方法:此项前瞻、单中心研究的入选标准为急性缺血性卒中发作24h表现出临床症状的患者。美国国立卫生研究院卒中量表≥3,无MRI禁忌症。回波平面成像(EPI)结合平行采集技术用于3T磁共振(MR)扫描以加速收集速度。2位神经系放射专家独立分析图像。

结果:62位患者符合入选标准,22位患者接受MRI扫描,共收集84份可供分析的MRI图像。诊断图像质量获得100%弥散加权成像。100%ERI-液体筛检反转恢复成像,98%EPI-梯度回波,90%颈部MR血管造影,96%脑部MR血管造影,94%动态敏感性对比灌注扫描一致性范围为0.64-0.84.59名患者(95%)患有急性梗死。

结论:诊断质量良好的六分钟核磁共振成像可用于评价急性缺血性脑卒中患者,并且与多通道计算层析成像相比,能显著减少扫描时间。

Ann Neurol:DWI不能很好诊断短暂性脑缺血发作

短暂性脑缺血发作(TIA)的诊断主要依据临床病史,因为神经系统体征常很快消失。核磁共振(MR)弥散加权成像(DWI)对微小缺血灶敏感的优点,有助于诊断短暂性脑缺血发作(TIA),并且TIA伴DWI急性缺血灶阳性的患者,卒中复发风险将会增加。因此DWI既有助于提高TIA的诊断,还能预测短期卒中风险。 目前国家卒中指南建议对TIA患者进行DWI检测。世界卫生组织提出了通过
