Abstract
A system and method for producing an image of a vasculature of a subject using a magnetic resonance imaging (MRI) system includes applying a saturation pulse to a prescribed imaging slice to substantially suppress MR signals in the prescribed imaging slice. A quiescent inflow time period (QITP) is observed that is at least equal to half a projected duration of a cardiac cycle of the subject. After the QITP, k-space data is acquired from the prescribed imaging slice, and a subset of the data representative of a desired portion of the cardiac cycle of the subject is reconstructed into an image of the subject including at least the prescribed imaging slice.
