Abstract
A system and method for producing an image of a vascular structure of a subject using a magnetic resonance imaging (MRI) system includes performing a first pulse sequence to acquire a flow-dependent imaging data set from the stack of prescribed imaging slices following a first quiescent inflow time period (QITP). The process also includes performing a second pulse sequence without suppressing signal from spins flowing into the stack of prescribed imaging slices through either of the veins or arteries to acquire a flow-independent imaging data set. The flow-dependent imaging data and the flow-independent imaging data are subtracted to create a difference image of the stack of prescribed imaging slices illustrating the at least one of the arteries and the veins as having a bright contrast and another of the arteries and veins as having a suppressed contrast.
