The current clinical standard of care currently requires separate DCE and MRA acquisitions to evaluate liver lesions and vasculature. New time-resolved imaging methods can produce a series of dynamic images with high temporal and spatial resolution. In this work we present a novel contrast enhanced imaging method to acquire both high resolution angiograms and high temporal resolution perfusion images of the liver in a single acquisition. This approach could eliminate the need for separate MRA and DCE injections and produces co-registered MRA and perfusion images to facilitate surgical and treatment planning.
