^sup 99m^Tc-[bis (dimethoxypropylphosphinoethyl)-ethoxyethylamine (PNP5)]-[bis (N-ethoxyethyl)-dithiocarbamato (DBODC)] nitride (N-PNP5-DBODC or N-DBODC5) is a new monocationic myocardial perfusion tracer. We sought to compare the myocardial uptake and clearance kinetics and organ biodistribution of ^sup 99m^Tc-N-DBODC5 with ^sup 99m^Tc-sestamibi and ^sup 99m^Tc-tetrofosmin. Methods: Seventy-five anesthetized Sprague-Dawley rats were injected intravenously with 22.2-29.6 MBq ^sup 99m^Tc-N-DBODC5 (n = 25), ^sup 99m^Tc-sestamibi (n = 25), or ^sup 99m^Tc-tetrofosmin (n = 25). Rats were euthanized at either 2, 10, 20, 30, or 60 min after injection and γ-well counting was performed on ...
