A method of producing a series of vasculature images over an extended field of view (FOV) larger than an FOV of an MRI system includes acquiring initial time-resolved image data from the vasculature and, during the acquiring process, reconstructing, in substantially real-time, a series of three-dimensional (3D) tracking images of the initial portion of the vasculature illustrating a current position of a contrast bolus in the vasculature as the contrast bolus passes through the initial portion of the vasculature. Based on a current position of the contrast bolus, the subject is moved to a subsequent imaging station to acquire subsequent time-resolved image data and reconstruct subsequent 3D tracking images of subsequent portions of the vasculature. This process is repeated and then an image is assembled that extends over the extended FOV using the initial time-resolved image data and the subsequent time-resolved image data.
