Cardiac MR strain imaging has been an active platform for the development of several non-invasive methods used to understand myocardial structure and function. Imaging myocardial strain is of growing importance in the assessment cardiovascular disease. Studies have shown myocardial strain is more predictive of future, adverse cardiac events than left-ventricular (LV) ejection fraction (EF) and studies have shown that MR strain imaging has the potential to demonstrate subclinical myocardial changes prior to the onset of myocardial dysfunction. This work reviews various strain imaging methods, the advantages, limitations and current clinical applications of these techniques.
