目的：探讨 Propl er 技术对减少头部运动伪影及磁敏感伪影的应用价值。方法我院于2010年3月至2013年对55例磁共振头颅检查时躁动或难以自控的患者，进行常规 FRFSE T2WI 和 Propel er T2WI 轴位扫描；对33例磁敏感伪影明显者行常规扩散加权图像（DWI）和Propel er DWI 扫描。观察并对照分析 FRFSE T2WI 和 Propel er T2WI 以及 DWI 与 Propel er DWI 的图像质量状况。结果通过 T2WI 检查55例，对存在明显运动伪影的患者行 Propel er T2WI 扫描后明显减少或消除了运动伪影，与 T2WI 检查结果相比差异明显，具有统计学意义（P<0.05）。DWI 检查33例患者有显著磁敏感伪影，采用 ProDel er DWI 后，与 DWI 检查结果相比差异明显，具有统计学意义（P<0.05）。结论应用 Propel er 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，值得推广应用。

Objective To study the Propl er technology to reduce the head motion artifact and the application value of the magnetic sensitive artifact. Methods Our hospital from March 2010 to 2013, 55 cases of MRI head check agitation or patients with difficult to control, for regular FRFSE T2WI and Propel er T2WI axial scanning; 33 cases of magnetic sensitive artifact obvious line of conventional diffusion weighted image (DWI) can and Propel er DWI scan can. Observation and contrast analysis FRFSE T2WI and Propel er T2WI and DWI and Propel er can DWI image quality can. Results Through T2WI check 55 cases of patients with obvious motion artifact line Propel er T2WI scan significantly reduce or eliminate the motion artifacts, clear difference compared with T2WI results, with statistical significance (P < 0.05). DWI examination can 33 patients had significant magnetic sensitive artifacts, adopting ProDeller DWI, can clear difference compared with DWI results can, with statistical significance (P < 0.05). Conclusion Application of Propel er technology can significantly reduce or eliminate T2WI and DWI on magnetic sensitive to motion artifacts and artifact can, is worthy of popularization and application.
