Doppler guidewire enables us to m s u r e phasic coronary velocity and has been used for the measurement of coronary flow reseme (CFR). Although CFR Is usuaiiy calculated by the quotient of peak flow velocity during papaverlne infusion and flow velocity at rest, this assumption Is true only H condui
## Abstract Myocardial blood flow (MBF) can be quantified using dynamic __T__~1~βweighted MRI of diffusible tracers and a mathematical model of underlying vasculature. Quantification of MBF by means of __T__~1~β weighted MRI requires knowledge of the arterial input function (AIF). The AIF can be es
