3D + time CMR localized strain analysis A 3D + time cardiovascular magnetic resonance (CMR) image created from 2D cine short -axis image stack. B, C 48 point left ventricular (LV) feature-tracking schematic with example images in short-axis (D) and long axis (E) views from a MATLAB-based graphical user interface. Example circumferential (Ecc; F), longitudinal (Ell; G), radial (Err; H), surface area (Ea; I) colorized strain maps at peak systole derived from 3D + time CMR images of a Duchenne muscular dystrophy (DMD) patient from MATLAB feature-tracking analysis. F–I also correspond to Additional files 1, 2, 3, 4. Scale bar = 1 cm
