A system and method for creating at least one angiographic image using a magnetic resonance imaging (MRI) system includes acquiring, with the MRI system and using parallel imaging techniques, a pre-contrast image data set and a post-contrast image data set of a portion of a subject having a vascular structure extending therethrough and subtracting the pre-contrast and the post-contrast image data set to generate a difference angiogram data set. The method includes reconstructing the difference angiogram data set into at least one aliased angiogram, creating a region of interest (ROI) mask from an image of the portion of the subject, and indicating a masking border surrounding the vascular structure and substantially excluding tissues surrounding the vascular structure. The method then includes de-aliasing the at least one aliased angiogram using the ROI mask to create an angiogram of the portion of the subject.
