Abstract
Captopril renography (CRS) with99mTc-DTPA and99mTc-MAG3 was performed on a 21-year-old woman with renovascular hypertension due to right renal artery stenosis caused by fibromuscular dysplasia. In the affected kidney, the renogram pattern was substantially changed with99mTc-DTPA and99mTc-MAG3 following the administration of captopril, and the quantitated renal uptake indicating individual renal function was significantly decreased in99mTc-DTPA and slightly decreased in99mTc-MAG3. In the contralateral normal kidney, the renogram showed some minor changes with both radioagents, while the quantitated renal uptake was significantly decreased with99mTc-DTPA and substantially increased with99mTc-MAG3. The combined use of physiologically different renal agents99mTc-DTPA and99mTc-MAG3 is helpful in investigating hemodynamic and functional changes in the stenosed kidney as well as the normal kidney in RVH.
