From: Functional measurements based on feature tracking of cine magnetic resonance images identify left ventricular segments with myocardial scar

Figure 2

Feature tracking of patient with extensive scar as shown in Figure 1. Upper left shows vector arrows of late systolic velocity tracing, 190 ms after QRS (green). Upper right shows radial strain tracing of the entire cardiac cycle. Blue represents the apex showing very low strain values; red is the normal posterior wall. Lower right displays longitudinal traces from the same locations, with postsystolic strain in the apex. Lower left is volume curve based on single plane Simpson (red) and emptying velocity (dV/dt), blue tracing.
