Fig. 8From: Simple motion correction strategy reduces respiratory-induced motion artifacts for k-t accelerated and compressed-sensing cardiovascular magnetic resonance perfusion imagingScore (a) and rank (b) comparisons among motion correction rigid k-t PCA/SLR, nonrigid k-t PCA/SLR and k-t FOCUSS reconstruction results by 2 experienced cardiologists. Five bars in each plot from left to right corresponds to motion corrected rigid k-t PCA and k-t SLR, motion corrected nonrigid k-t PCA and k-t SLR, and motion corrected k-t FOCUSS. The scale of the scores range from 1 (very poor) to 5 (very good) and the scale of the ranks range from 1st to 5th. Error bars indicate the standard deviation, and * indicate the significance between rigid k-t PCA/k-t SLR and other methods Back to article page
