Increased Patchy Renal Accumulation of <sup>99m</sup>Tc-Methylene Diphosphonate in a Patient with Severe Loin Pain after Exercise

Abstract

Radionuclide imaging in a patient who had acute renal failure with severe loin pain and patchy renal vasoconstriction is described. The patient was studied 3h after the intravenous bolus injection of 25 mCi99mTc-methylene diphosphonate (99mTc-MDP). An intense patchy renal concentration of 99mTc-MDP was observed.
