LGE example images with corresponding ex vivo TTC staining. Selected LGE images and corresponding TTC sections from four animals (rats 2 hours post reperfused MI). LGE and TTC agree closely through the range of infarct sizes shown. TTC stains viable myocardium red leaving the infarct area white. In addition, the first 3 hearts were also stained for perfusion with Evans blue prior to TTC.
