Fig. 2.

Examples of strain curves from circumferential (Ecc), radial (Err) and longitudinal strain (Ell) from the same patient using tagging, displacement encoding with simulated echoes (DENSE) and three feature tracking programs; The average cardiac cycle length is 844 ms. There are fewer phases in tagging and in DENSE imaging due to degradation of tags in diastole and incomplete diastolic acquisition from prospective ECG gating, respectively
