Figure 7.

The myocardial infarction region is revealed through the elevated signal intensity of LGE at the subendocardium of the basal-posterior part of the heart (yellow arrow, left). The calculated radial (middle) and longitudinal (normal to the plane, right) strains show a clear strain difference between the infarcted area and its neighboring regions. This figure shows that the proposed method is able to reveal the impairment caused by infarction in the through-plane strain. As expected, the lack of contraction in one region extends beyond its boundary through its mutual connection to the rest of the continuum.
