LV wall thickening, the main factor of systolic ejection, is reflected in radial strain. This strain was locally measured in this study, from the circularly tagged images, through a K-space based compression encoding method. The results were compared to the strain measurement from HARP and general agreement was confirmed. The proposed method does not need to any tracking or differentiation for strain measurement and therefoere, it has potential advantages over other methods in practicality, computational cost and accuracy.
