Inflow slab-selective (SS) inversion-recovery (IR) 3D imaging has been widely used for non-contrast-enhanced (NCE) renal MR angiography, but with limited craniocaudal coverage due to the usability of upstream arterial blood only. We propose a novel NCE MRA method that allows visualization of renal and abdominopelvic arteries over a large field-of-view. This is achieved by employing a velocity-selective inversion preparation that preserves arterial blood within the imaging volume while inverting background tissues. The capability of the proposed method to depict various abdominal arteries is demonstrated in-vivo with a comparison to the SS IR method.
