Comparison of Ablation Zone Between 915- and 2,450-MHz Cooled-Shaft Microwave Antenna: Results in In Vivo Porcine Livers

Abstract

The 915-MHz cooled-shaft microwave antenna can lead to deeper penetration of liver tissue and can yield a significantly larger ablation zone than the 2,450-MHz cooled-shaft antenna in in vivo porcine livers. In light of the result, 915-MHz cooled-shaft microwaves may be more effective for tumor ablation, especially for large tumors.
