Typical and atypical appearance of microwave ablation zones in the liver

Abstract

Local minimally invasive interventional procedures such as radiofrequency ablation (RFA) and microwave ablation (MWA) for the treatment of both primary hepatic malignancy and liver metastases of various origins have become increasingly popular in recent years. After treatment, is then the task of follow-up imaging with computed tomography (CT) and/or magnetic resonance imaging (MRI) to evaluate treatment success and to be aware of possible pitfalls that might give rise to misinterpretation.
