High spatial and temporal resolution are desired in abdominal CE-MRA, which is particularly challenging due to the limited scan time and need to image over a large FOV. In this work an abdominal CE-MRA method for high spatial and temporal resolution imaging is developed that implements the CAPR sampling method, high (R8) SENSE accelerations and specialized receiver coil arrays. Volunteer and patient studies have been performed using an imaging protocol that consists of a low-dose (2 ml) time-resolved 3D CAPR acquisition that provides an overview of the vasculature and serves as a timing bolus for a subsequent high spatial resolution single phase CAPR renal MRA.
