  		Fig. 1A. —CT angiographic images of 36-year-old man living renal donor whose left kidney was donated. Surgeons confirmed presence of three arteries and single vein. Anterior CT angiographic images reconstructed using thick-slab volume rendering (A) and maximum intensity projection (B) show two arteries (arrows) and one vein (arrowheads) in left kidney.

  		Fig. 1C. —CT angiographic images of 36-year-old man living renal donor whose left kidney was donated. Surgeons confirmed presence of three arteries and single vein. Oblique coronal CT angiographic images reconstructed using sliding thin-slab volume rendering (C) and maximum intensity projection (D) reveal one additional artery (arrowheads) that was missed on thick-slab reconstructions (A and B).

  		Fig. 2A. —CT angiographic images of 27-year-old man living renal donor whose left kidney was donated, Surgeons confirmed presence of one supernumerary artery with early branching artery and single vein. Anterior CT angiographic images reconstructed using volume rendering (A) and maximum intensity projection (B) show one supernumerary artery (arrows) and single vein (arrowheads) in left kidney.

Oblique coronal CT angiographic images reconstructed using sliding thin-slab volume rendering (C) and maximum intensity projection (D) reveal early branching artery extending from supernumerary artery (arrowheads) that was missed on thick-slab reconstructions (A and B).
