AMERICAN JOURNAL OF ROENTGENOLOGY. Fusion Imaging–Guided Radiofrequency Ablation for Hepatocellular Carcinomas Not Visible on Conventional Ultrasound

Kyoung Doo Song, Min Woo Lee, Hyunchul Rhim, Dong Ik Cha, Yousun Chong and Hyo K. Lim

OBJECTIVE. The objective of our study was to assess whether fusion imaging of conventional ultrasound and liver CT or MR images can improve the conspicuity of lesions and feasibility of percutaneous radiofrequency ablation (RFA) for the treatment of hepatocellular carcinomas (HCCs) not visible on ultrasound. Whether peritumoral anatomic landmarks can be used for the placement of an electrode in HCCs not visible on ultrasound even after image fusion was also evaluated.
