A method of characterizing myocardial perfusion pathology by analyzing a plurality of medical images of at least a portion of the heart of a subject of interest (20), acquired in a consecutive manner by a medical imaging modality (10), the method comprising steps of: sampling intensities of selected myocardial image positions from the plurality of medical images and assigning an index representing an order of acquisition to the respective sampled intensities of the myocardial image positions to obtain intensity curves (60) and—calculating an index number (64, 66) indicative of a spatio-temporal perfusion inhomogeneity or perfusion dephasing among at least a subset of myocardial segments of the plurality of myocardial segments, based on the obtained intensity curves (60) a system (52) for myocardial perfusion pathology characterization by analyzing a plurality of medical images by carrying out such method a medical imaging modality (10) comprising such system (52) a software module (48) for carrying out such method.
