In breast or thoracic-spine MRI, motion artifacts due to cardiac- or aortic-pulsation inevitably appear, particularly in the images after contrast media injection. Such artifacts can impede the diagnosis. In this study, we proposed a new technique for simply and effectively reducing cardiac/pulsatile motion artifacts on contrast-enhanced images by using a cylindrical labeling inversion pulse which can be combined with various sequences.
