Description Computed tomography (CT) is considered an upcoming technology for the quantitative estimation of myocardial perfusion (MPF). Based on previous results that affirm the feasibility of estimating global MPF using a CT scanner in an animal model, this work evaluates the computation of MPF in patients by comparing two different mathematical approaches based on the indicator dilution method. The first, the so called upslope method, was already used in the previous study, the second uses a deconvolution model which possibly is more suitable in the evaluation of regional MPF measurements. A good correlation between both methods could be found and the quantitative results of both methods correspond well to myocardial perfusion values as described in the literature.
