Myocardial blood flow of first-pass MR perfusion was estimated using a simple mathematic model in constrained devolution that accounts for loading of the interstitial space with gadolinium contrast. The results of the MR perfusion estimates correlated with a wide range of absolute blood flow measured from microsphere references.
