Answer

Renal scintigraphy with technetium-99m mercaptoacetyltriglycine (99m Tc MAG3) demonstrates delayed elimination of the tracer and increased residual activity consistent with tubular dysfunction in HIV nephropathy. These abnormalities correlated with creatinine clearance.

On renal gallium scanning, increased signal indicates inflammation in patients with HIV nephropathy and is correlated with proteinuria.
