Figure 1: Technetium-99 m ethylenedicysteine renal scintigraphy: (a) Flow images showed normal perfusion in left renal fossa and impaired perfusion in right renal fossa, (b) cortical uptake images revealed normal uptake in left kidney with pseudo-impression of impaired uptake in right kidney. Prevoid (c), postvoid (d), and delayed 3-h (e) static images showing the progressive tracer clearance from both renal fossa. Posterior (f) and anterior (g) images at 5-h showed mild tracer retention in the right renal fossa
