Poor technetium-99m-DMSA renal uptake with near normal technetium-99m-DTPA uptake caused by tubulointerstitial renal disease.
We present a patient with tubulointerstitial renal disease and poor renal 99mTc-DMSA uptake. A 99mTc-DTPA scan was normal and the creatinine clearance only minimally decreased. In this case, 99mTc-DMSA uptake did not correlate with "global renal function," but rather with the functioning tubular mass.
