After the motion correction the k-space is the precessed by SW-CG-HYPR method for the time-resolved myocardial perfusion images. figure omitted; refer to PDF Results The average image quality score of the free-breathing images with motion correction (3.09 ± 0.37) is significantly higher than those without motion correction (2.26 ± 0.40), and is comparable to the successful breath-holding images (3.10 ± 0.41) (Figure figure omitted; refer to PDF ).
