Intra-scanner repeatability of global and regional myocardial strain measures on the MARTINOS dataset. (A) Circumferential (CIRC) and radial (RAD) strain and strain rate (SR) curves across time derived from two different acquisitions (ACQ). Four representative healthy subjects are shown, including the correspond cine images used for analyses. (B) Polar maps for all subjects were used to evaluate the relative change and absolute relative change across polar map segments. Circles represent peak systolic and early-diastolic strain values. Stars represent peak late-diastolic strain values.
