Non-contrast-enhanced (NCE) abdominal MR angiography (MRA) with large spatial coverage is clinically desired. The current method using spatially selective inversion (SSI) pulse to null static tissue and blood is only limited to small field of view (FOV) due to its sensitivity to slow arterial inflow. Velocity-selective inversion (VSI) based approach was shown to preserve the arterial blood inside the imaging volume at 1.5T. In this study, a novel strategy of VSI + VSS was proposed for abdominal MRA of large FOV, and its advantage over SSI based approach was demonstrated among healthy subjects at 3T.
