title: Evaluation of the renal clearance of technetium-99m PAHIDA in dogs.
abstract: The renal clearance of the technetium-99m complex of para[(biscarboxylmethyl)-aminomethylcarboxyamino]hippuric acid ([99mTc]PAHIDA), has been previously studied in rodents and falls between that of [99mTc]DTPA (diethylenetriaminepentaacetic acid) and iodine-131 (131I) orthoiodohippuran (OIH). To investigate the effect of species variation, the plasma clearance of [99mTc]PAHIDA was investigated in dogs. The plasma disappearance of the renal agent approached that of [99mTc]DTPA and was significantly less than that of OIH. Despite the structural similarities of the PAHIDA ligand and aminohippurate, the [99mTc]PAHIDA complex undergoes little, if any, tubular secretion in the canine kidney.
