MR first pass perfusion imaging via the dynamic enhancement after intravenous contrast injection has become a valuable clinical tool for the assessment of myocardial perfusion. The aim of the present study was to investigate whether such a saturation effect of myocardial T1 has to be taken into account in MR-based perfusion studies involving multiple injections of Gd-DTPA.
