PE-duramycin imaging. Increased 99mTc-Duramycin uptake is seen in acute myocardial infarction of the rat at 120 min post-i.v. injection with excellent infarct-to-non infarct activity ratio (right). Autoradiography confirmed radioactivity uptake within the myocardial infarction. No tracer uptake is seen in the healthy rat (left). B, bladder; K, kidney. Courtesy of Pr.
