The aim of this study was to compare at 3.0T SR-TrueFISP and SR-TurboFLASH pulse sequences for semi-quantitative and absolutequantitative assessment of the myocardial perfusion reserve. No differences were found in SNR and CNR between both pulse sequences. However, SR-TrueFISP yielded superior reproducibility than SR-TurboFLASH as well as absolutequantification using the MMID4 model yielded lower intraobservervariability than the semiquantitative method.
