Non-contrast enhanced MRA of abdominopelvic arteries within a large field of view is very challenging due to rapid blood flow and variant flow speed among different subjects. Simultaneous Non-contrast Angiography and intraPlaque imaging (SNAP), a non-contrast enhanced MRA technique, provides reliable imaging for the carotid and intracranial arteries. In this study, we sought to explore the feasibility of SNAP with compressed sensing acceleration in abdominopelvic arteries imaging. The complementary information provided by different scans with different velocity sensitivities can be combined to obtain reliable abdominopelvic MRA with a large coverage.
