Imaging of the Liver Following Interventional Therapy for Hepatic Neoplasms

Locoregional therapies for hepatic neoplasms have distinctive imaging features after treatment, different from those observed after systemic therapy. As these therapies are becoming more common, it is important that radiologists be aware of the imaging appearance of tumors after locoregional therapies to correctly diagnose treatment response or failure and potential complications. This article reviews the imaging recommendations and findings after intra-arterial therapies (chemoembolization and radioembolization) and ablative therapies.
