Comparison of SPAMM, HARP and DENSE in a Deformable Phantom

A number of techniques are available for the measurement of displacement and strain in the heart including SPAtial Modulation of Magnetization (SPAMM) (1) followed by tag line detection, CSPAMM followed by HARmonic Phase (HARP) analysis (2), and Displacement ENcoding with Stimulated Echoes (DENSE) (3). However, it is unclear which method gives the most accurate results in practice.
