[Experimental evaluations of ther preferential use of Tc99m and In113m in hepatic scintiscanning]

A hollow perspex dummy was filled with radioactive fluid to simulate the liver, cold nodes being represented by paraffin balls of diameter varying from 2.5 to 4.0 cm, variously located. Scans were carried out with a linear scanner using 99mTc and 113mIn as tracers. Advantages and drawbacks of the two tracers in demonstrating cold areas in the liver are compared and discussed.
