The stiffness in the myocardium represents a reliable biomarker of cardiac dysfunction or diseases, such as atherosclerosis or cardiac infarction. Actually, there exist methods to retrieve this indicator using MRI, however, they can be very time-consuming, especially for volumetric evaluations. In this work, we propose a novel method to estimate strains using Phase-Contrast or 4D-flow data, where velocity fields are transformed into strain tensors in a numerically simple but robust manner. Preliminary results are promising and we expect to validate our method in volunteers and patients.
