The Motion Artifact Suppression Technique (MAST) is a method which uses a series of gradient echos that are computed to cancel velocity, acceleration and pulsatility components of involuntary motion in MR imaging. A total of 916 patient studies were performed over a nine month period using MAST sequences with a TE 40, 60, 80, 100, 120, and 26/112. There was considerable improvement in long TR, long TE images. Cerebrospinal fluid flow artifacts were reduced. Body and spine images had reduced flow and respiratory artifacts. Spin rephasing in blood vessels caused increase intraluminal signal. This might be useful for cardiovascular imaging.
运动伪影抑制技术（MAST）是一种利用一系列梯度回波来消除磁共振成像中非自主运动的速度、加速度和搏动性成分的方法。在九个月的时间里，使用TE为40、60、80、100、120以及26/112的MAST序列对916例患者进行了研究。在长TR、长TE图像方面有显著改善。脑脊液流动伪影减少。身体和脊柱图像的血流和呼吸伪影减少。血管中的自旋重聚导致管腔内信号增加。这可能对心血管成像有用。
