Both high spatial and temporal resolution are desired for contrast-enhanced MR angiography (CE-MRA). In this work, we describe a technique that combines interleaved variable density (IVD) Cartesian sampling, ARC parallel imaging (PI), and Cartesian HYPR reconstruction. This technique is validated in multiple exams performed on healthy volunteers.
