"reduction in peak systolic strain, systolic lengthening and post-systolic shortening"
"MR tagging has been used for quite some time with the main advantage that deformation is directly measured by myocardial tissue properties, but with the offset of low temporal resolution, extra acquisition time, time-consuming post-processing etc. 4."
"MR feature tracking is a post-processing technique, which can be used on normal cine SFFP sequences, without additional acquisition time or complicated post-processing software. The main advantage is the ease of use. The downside is low spatial and temporal resolution and the tracking algorithm is only based on contours."

"Post-processing"
"Circumferential strain represents the myocardial contraction along the circular outline in the short axis. It is negative in normal individuals since the circumference of the left ventricle in a relaxed state L0 decreases in systole 2,3."
"Longitudinal strain is the deformation of the left ventricle in the z-direction that is from the base or annular ring to the apex usually resulting in a negative strain since the left ventricular chamber length (L) in systole is shorter than the respective length (L0) at baseline in the normal heart 2,3."
"Circumferential strain represents the myocardial contraction along the circular outline in the short axis. It is negative in normal individuals since the circumference of the left ventricle in a relaxed state L0 decreases in systole 2,3."
"Left ventricular torsion is measured in degrees and is related to the clockwise twirl from apex to base and an anticlockwise rotation from the base to the apex as well as to the circumferential-longitudinal shear angle 3."
