A method for analyzing a dynamic contrast-enhanced magnetic resonance image: acquiring an angiographic contrast agent concentration time signal AIF in dynamic contrast magnetic resonance imaging (DCE-MRI) data; performing non-linear least square sum fitting of a full shutter speed model SSMfull model and a simplified vascular shutter speed model SSMvas model for a DCE-MRI time series signal of each pixel point respectively to obtain DCE-MRI signal fitting results; using a modified Akaike information criterion to score and compare the DCE-MRI signal fitting results, and selecting the optimal model; when the optimal model is the SSMfull model, generating a distribution map of the five groups of physiological parameters Ktrans, pb, po, kbo and kio after fitting; when the optimal model is the SSMvas model, generating a distribution map of the three groups of physiological parameters Ktrans, pb and kbo after fitting; and performing error analysis on kio and kbo to generate a final distribution map of the parameters kio and kbo, and a final distribution map of the parameters Ktrans, pb and po. The described analysis method may improve the accuracy of the estimation of the five physiological parameters of Ktrans, pb, po, kbo, and kio.
