MRA (MIP) of normals kidneys, with a single artery to each kidney. The other structure at the left hilum is venous contaminant.
MRA or CTA of the kidneys may be performed in the pre-procedural assessment for renal denervation (ablation) procedures, as well as to assess for renal artery stenosis in hypertensive patients.
