Magnetic resonance imaging of the upper abdomen has been hampered by motion artifacts that cause suboptimal image quality. A promising software solution to this problem, motion artifact suppression technique (MAST), is described. Using mathematically determined refocussing gradients, it has improved image clarity significantly. Unlike alternate techniques such as respiratory gating, there is no increase in scan time, and patient throughput is expedited.
上腹部的磁共振成像一直受到运动伪影的影响，导致图像质量欠佳。本文描述了一种针对该问题颇具前景的软件解决方案——运动伪影抑制技术（MAST）。通过数学确定的重聚焦梯度，它显著提高了图像清晰度。与呼吸门控等其他技术不同，扫描时间没有增加，并且加快了患者检查通量。
