Measurement of extent of myocardial injury and myocardial function. Segmentation of left ventricle when measuring extent of myocardial injury from late gadolinium enhancement imaging (A) and T2 weighted imaging (B). Representative images of measuring global longitudinal strain (C) and twist (D) from speckle tracking echocardiography. Arrow in (A) indicates LGE and arrow head indicates microvascular obstruction. Arrows in (B) indicate higher signal intensity which represents myocardial edema.
