This thesis focuses on MR perfusion in the detection of myocardial ischemia and used protocols in this respect. In patients with no prior myocardial infarction an adenosine “stress”-only technique can reliably exclude significant myocardial ischemia in a large patient group in a protocol time of only 15-20 minutes. Using systematic reading criteria for a visual analysis of perfusion images considerably improves agreement with an expert reader. In a post-infarct setting improvements in time can be achieved by reducing post-processing of a stack of short-axis cine images by analysing only every second short-axis series for global left ventricular functional parameter assessment. In this respect, specificity of a dobutamine stress MR examination can be increased by performing a perfusion sequence on peak dose dobutamine. For imaging at higher heart rates, a TSENSE first-pass perfusion sequence may play a role to maintain enough spatial coverage.
