Localization of the renal cortical imaging agent 99mTc-Sn-DMSA in the bowel

Renal imaging in 2 patients with severe renal disease (serum creatinine greater than 10 mg/dl) showed deposition of 99mTc-Sn-DMSA in the bowel. Like 203 Hg-chlormerodrin, this radionuclide may be associated with a hepatobiliary excretory mechanism in patients with renal impairment.
