✓ Experimental thermal lesions were produced in the liver and brain of rats and rabbits by induction-heating, radiofrequency electrocoagulation, and surface-heating. Pathological examination revealed similar destructive changes from all three methods and demonstrated that lesions were essentially similar in histological character. The safety of different techniques appears to be more related to technical problems in the generation of the lesions than to the physical characteristics of the lesions themselves.
