Contrast-enhanced magnetic resonance myocardial perfusion imaging is a very promising concept for the noninvasive detection of coronary artery disease. The Aim of this work was to investigate and compare the two for myocardial perfusion imaging established pulse sequences SR-TurboFLASH and SR-TrueFISP at 1.5T and 3.0T. The pulse sequences and field strengths were compared with regard to SNR and CNR as well as for their intra-observer variability in absolute quantification of the myocardial blood flow. SR-TrueFISP at 3.0T yielded highest SNR and CNR values as well as the lowest intra-observer variability.
