To describe a novel hardware MR-perfusion phantom to model first-pass of a bolus of contrast in the cardiac cavities and large thoracic vessels (arterial input function, AIF) and in the myocardium, allowing for the acquisition of dynamic first-pass MR-perfusion data and for a precise control of card

## Abstract Accurate and fast quantification of myocardial blood flow (MBF) with MR firstβpass perfusion imaging techniques on a pixelβbyβpixel basis remains difficult due to relatively long calculation times and noiseβsensitive algorithms. In this study, Zierler's central volume principle was used
First-pass contrast-enhanced myocardial perfusion MRI in rodents has so far not been possible due to the temporal and spatial resolution requirements. We developed a new first-pass perfusion MR method for rodent imaging on a clinical 3.0-T scanner (Philips Healthcare, Best, The Netherlands) that emp
## Abstract ## Purpose To compare fully quantitative and semiquantitative analysis of rest and stress myocardial blood flow (MBF) and myocardial perfusion reserve (MPR) using a dualβbolus firstβpass perfusion MRI method in humans. ## Materials and Methods Rest and dipyridamole stress perfusion i
## Abstract ## Purpose To study the nonlinearity of myocardial signal intensity and gadolinium contrast concentration during firstβpass perfusion MRI, and to compare quantitative perfusion estimates using nonlinear myocardial signal intensity correction. ## Materials and Methods The nonlinearity
