In the field of ultra-high field MRI, T2* mapping is a promising technique for the non-invasive assessment of myocardial pathophysiology. Preclinical studies have already shown the potential to detect structural changes in infarcted myocardial tissue. Quantitative T2* imaging is very demanding with regard to measurement- and postprocessing time. Hence, we compared in this study the simpler and faster grayscale analysis of T2*-weighted images with quantitative T2* techniques. This was done in early and late acute infarct healing stages in a large animal model by comparing T2* maps with grayscale T2*-weighted images.
