Contrast-enhancement techniques allow the visualization of small myocardial injuries in acute myocarditis, which cannot be detected by any other noninvasive technique. Late Gadolinium Enhancement (LGE) has been shown predictive for the development of heart failure. Early Gadolinium Enhancement (EGE) was identified as parameter for detection of disease activity. We analyze the contrast agent washout during 10 minutes after tracer administration. Our aim is to characterize parameter values of patients with myocarditis in a 3D spatially distributed contrast agent flow model.
