3D + time CMR-derived localized systolic strain rate can discriminate between DMD patients (n = 43) and healthy control (n = 25) subjects. A, B Schematic representation of localized longitudinal strain (Ell) and strain rate. C Example 4D CMR long-axis image slice depicting feature-tracked endocardium (blue) and epicardium (green), D Localized peak Ell between DMD patients and healthy control subjects less significant than peak Ell, however E Ell systolic strain rate (normalized to cardiac cycle) shows significant differences between healthy control subjects and DMD patients in all regions. **p < 0.01, ***p < 0.001, error bars depict median and interquartile range
