Abstract Cardiovascular magnetic resonance (CMR) is currently the gold standard for assessing both global and regional myocardial function. New tools for quantifying regional function have been recently developed to characterize early myocardial dysfunction in order to improve the identification and management of individuals at risk for heart failure. Of particular interest is CMR myocardial tagging, a non-invasive technique for assessing regional function that provides a detailed and comprehensive examination of intra-myocardial motion and deformation. Given the current advances in gradient technology, image reconstruction techniques, and data analysis algorithms, CMR myocardial tagging has become the reference modality for evaluating multidimensional strain evolution in the human heart. This review presents an in depth discussion on the current clinical applications of CMR myocardial tagging and the increasingly important role of this technique for assessing subclinical myocardial dysfunction in the setting of a wide variety of myocardial disease processes.

Introduction Heart failure (HF) is the result of advanced myocardial dysfunction and continues to be a leading cause of morbidity and mortality in developed nations. In the United States alone, an estimated 5.3 million adults carry the diagnosis of HF and the disease prevalence continues to escalate with aging of the population. In addition to conferring a significant burden of illness to affected individuals, management of HF also imposes enormous expense to the health care system [1]. Therefore, the ability to identify individuals at risk for developing HF - those who might benefit from targeted preventive interventions would be of immense value. To this end, some of the most promising approaches to improved risk stratification involve u
