Comparison of ablation zone between 915- and 2,450-MHz cooled-shaft microwave antenna: results in in vivo porcine livers.
OBJECTIVE
The objective of our study was to compare the ablation zones of two cooled-shaft microwave antennae-one operating at 915 MHz and one operating at 2,450 MHz-in in vivo porcine livers.


CONCLUSIONS
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.
