In patient 1, 99mTc-MAG3 scan revealed slightly decreased perfusion, extraction and excretion of the radioactive tracer (Figure 1A). In patient 1, the scintigraphy revealed a mild improvement in the perfusion, extraction, and excretion capability of both kidneys (Figure 1B).
99mTc-MAG3 renal scintigraphies of patient 2 at 2005 (A) and at 2007 (B). Note that at the end of the 2-year follow-up both renal scintigraphies show an improvement of the peak time and a significant improvement in the transit and excretion of the radionuclide in both kidneys (especially in patient 2).

In patient 2, 99mTc-MAG3 scans also showed poor perfusion, decreased and delayed radioactive tracer accumulation, as well as poor excretion (more severe than that of patient 1) (Figure 2A). In the second patient, the control scintigraphy revealed significant improvement in the perfusion, extraction, and excretion capability of both kidneys (Figure 2B).
