Imaging assessment after SBRT for hepatocellular carcinoma

Abstract

The use of stereotactic body radiotherapy (SBRT) in hepatocellular carcinoma (HCC) has increased over the past few decades. Thus, accurate evaluation of post-SBRT treatment response is essential to avoid over-treatment of responders as well as missing the opportunity to salvage non-responders. There are some intricate imaging differences after liver SBRT compared to those observed after conventional fractionated radiotherapy and other locoregional treatment. We aim to review the imaging changes that occur following SBRT for HCC and their potential clinical implications.
