Representative example of a patient with iLVNC. Measurement diagram of the peak systolic strain value of the left ventricular myocardium using DRA (a-h) and FT (i-p) in the same patient. Images a-c, i-k show the tracking contours of longitudinal strain based on the long axis in the 2-, 3- and 4-chamber view using DRA and FT, respectively. Images e-g, m-o show the segmental longitudinal strain values of the previous three images, respectively. Images d and l show the strain values of 16 segments in the radial direction using DRA and FT, respectively, which are derived from the short axis view. Images h and p show the strain values in the circumferential direction using DRA and FT, respectively, which are also derived from the short axis view
