摘要 目的:探讨Propeller技术对减少头部运动伪影及磁敏感伪影的应用价值。方法:对53例磁共振头颅检查时躁动或难以自控的患者行常规FRFSE T2WI和Propeller T2WI轴位扫描;对31例常规扩散加权图像(DWI)磁敏感伪影明显者进行Propeller DWI扫描。观察并对照分析FRFSE T2WI和Propeller T2WI以及DWI与Propeller DWI的图像质量状况。结果:53例在T2WI存在明显运动伪影的患者,在行Propeller T2WI扫描后明显减少或消除了运动伪影,图像质量级别显著升高[(2.88±0.32,(1.11±0.30),P=0.00)]。31例在DWI有显著磁敏感伪影的患者,采用Pro-peller DWI后,明显消除磁敏感伪影,图像质量明显提高[(2.84±0.35,(1.06±0.17),P=0.00)]。结论:应用Propeller技术能够明显减少或消除T2WI及DWI上运动伪影及磁敏感伪影,显著改善图像质量。
