    【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. ...... 濠碘€冲€归悘澶愬箖閵娿儲韬ù锝堟硶閺併倝骞嶇€ｎ偅绨氱紒娑橆槹缁侊妇鎲撮崼鐔割槯闁哄啰濮电涵鍫曞蓟閵壯勭畽闁瑰瓨鐗旂粭鍛姜閽樺寮块柡鍌氭祫缁辨繈宕ｉ婵嗗幋闁哄嫷鍨甸～锕傚箹濠婂懎鍋嶇€殿喗娲橀幖鍛婂緞鏉堚晜鍩傞柍銉︾矎濞村棝鎯嶆担娴嬪亾濠垫挾绀夐悹鍥棑閸嬶綁宕欑拠鑼綄妤犵偞娲樺〒鑸电▔鐎ｎ偅鐓欓柣銊ュ閳ь剚绮庨弫鎼佹嚇閹寸姴顣奸柍銉︾箖閸ㄣ劑鍨惧⿰鍐ㄦ枾缂傚啯鍨块妴澶愬灳濠靛⿴鍟忛梻鍌ゅ枔閳ь剨鎷�
