Hepatic Microwave Ablation in Challenging Locations

Seminars in Interventional Radiology, 2019
AbstractIn recent years, there has been increased utilization of microwave ablation (MWA) in the treatment of soft tissue tumors. MWA has several theoretical advantages over radiofrequency ablation (RFA) by achieving a more rapid and sustained heating of tissues, increased efficacy in tissues with poor thermal conductivity, and less susceptibility to ...
