Evaluation of the renal scanning agent N-succinyldesferrioxamine B in dogs

The mechanism of the excretion of 67 Ga-N-succinyldesferrioxamine B (SDF) was investigated in five healthy dogs. Comparison of the SDF clearance rates for whole blood and plasma as well as SDF renograms with those of 131 I-o-iodohippuric acid (OIH) and 111In-diethylenetriamine-pentaacetic acid (DTPA) revealed that SDF is cleared by glomerular filtration and not by an active tubular transport mechanism.
