Displacement ENcoding with Stimulated Echoes (DENSE) and HARmonic Phase (HARP) analysis of Complementary SPAtial Modulation of Magnetization (CSPAMM) data have been proposed for cardiac motion analysis. Following the insight of the Fourier shift theorem, it has been argued that the information content of DENSE and HARP should be identical. In this study, DENSE and HARP data were obtained consecutively in the same subjects and compared in terms of circumferential shortening, rotation and time-to-peak motion of the heart with and without employing signal peak combination.
