摘要
磁共振成像中所产生的伪影会严重影响图像的质量及对病灶的精确识别。对磁共振成像中各种伪影形成的原因及抑制方法进行阐述。大量研究表明,怎样快速有效地抑制各种原因产生的伪影,仍然是研究人员所面临的一个非常棘手的问题。因此,还需不断寻求新的方法及思路来解决这一难题,为医学观察和临床诊断提供可靠的依据。
The artifacts in magnetic resonance imagines（MRI） seriously degrade the imagine quality and affect the exact diagnosis. The reasons that may cause artifacts in magnetic resonance imaging and the suppressing methods are presented in this paper. One of the intractability appeared in researches is how to restrain all kinds of artifacts quickly and efficiently. It is important to search for new methods to solve this problem. It may provide reliable basis for medical observation and clinical diagnosis.
