in seven dogs we compared the quality of blood-pool images obtained with tcdx of different molecular weights ( 4 x 10 ( 4 ) = dx-40 ; 5 x 10 ( 5 ) = dx-500 ; 2 x 10 ( 6 ) = dx-2000 ) and with tc-99m red blood cells ( tcrbc ) labeled in vitro , and determined the organ distribution of this new agent by whole-body scanning and blood sampling .
