Abstract
Neuroendocrine tumors are an indolent, heterogeneous group of tumors that primarily
arise from the gastropancreatic tract and lungs. Most patients present with liver
metastases at the time of diagnosis, which cause significant morbidity and mortality
due to excess hormone secretion, bile duct obstruction, and liver damage. A small
percentage of these patients are eligible for potential cure through surgical resection.
However, interventional radiology provides liver-directed therapies, such as percutaneous
ablation, transarterial embolization, chemoembolization, and radioembolization, for
palliative care and potential bridging to debulking and surgical resection of neuroendocrine
liver metastases. This article aims to provide a brief overview of these liver-directed
therapies focusing on the pre-, intra-, and postprocedural imaging findings.
