    【摘要】目的：探究磁共振伪影的成因及其处理方式。方法：回顾性分析我院13例典型磁共振伪影图像，分析成因及处理方式。结果：磁共振伪影发生率为1.05%，共出现7种磁共振伪影，分布情况：射频伪影、化学位移伪影、卷摺伪影各1例，射频场不均匀伪影、梯度系统故障产生伪影各2例，主磁场不均匀伪影、运动伪影各3例。结论：在进行磁共振成像诊断中，应该采用积极措施避免伪影的出现，提供优质的临床诊断依据。

    Causes and treatment of MRI artifacts

    【Abstract】Objective: To explore the causes of artifacts and magnetic resonance approach. Methods: A retrospective analysis 13 cases of typical magnetic resonance image artifacts, analyzing the causes and treatment in our hospital. Results: MRI artifact rate was 1.05%, there were, seven kinds of MRI artifacts, distribution: RF artifacts, chemical shift artifact, Volume discount artifacts in 1 case, non-uniform RF field artifacts, gradient system failures produce artifacts in 2 cases, the main field inhomogeneity artifacts, motion artifacts in all three cases. Conclusion: During magnetic resonance imaging diagnosis, should adopt positive measures to avoid the appearance of artifacts, providing high-quality clinical diagnosis. ......
