B) Each of the real size 3D-printed pieces after being painted, red for the arterial system, blue for the venous system and orange for the kidney. All three regions were dockable and detachable. C) The physical kidney models were compared to the 3D reconstruction and the patient radiology data to confirm spatial coherence.
