Figure 1 ceMRI and Strain Imaging in Nontransmural Infarction
Contrast-enhanced magnetic resonance imaging (ceMRI) image (left), color-coded short-axis radial strain images at end-systole (middle), and radial strain tracings (right) for 1 cardiac cycle obtained from the same short-axis view in a patient with severe hypokinesia of the posterolateral wall. Contrast-enhanced magnetic resonance imaging indicates nontransmural infarction with less than 25% hyperenhancement. The 6 tracings for the 6 evaluated segments within the circumference demonstrate reduced peak negative systolic radial strain of the posterolateral wall. The segment demonstrated functional recovery after successful interventional revascularization of an occluded left circumflex artery.
