Introduction: The proliferation and increased use of 3.0 T MR Systems offers both potential advantages and difficulties in the implementation of unenhanced MRA techniques. Materials and Methods: To perform an initial feasibility study followed by technical optimization of quiescent interval single shot (QISS) magnetic resonance angiography for renal artery and lower extremity evaluation. The study was performed with IRB approval. Seven healthy volunteers underwent combined unenhanced Renal and Peripheral Lower Limb Angiography Conclusion: We report the feasibility of the QISS technique as a potential MRA technique for combined dual Renal and Lower extremity unenhanced MRA at 3.0 T
