Elf AK, et al. - Researchers performed this randomized study to assess the relative therapeutic response and safety after radioembolization (RE) and bland hepatic arterial embolization (HAE). In addition, they investigated early therapy-induced changes with diffusion-weighted MRI (DWI-MRI). After 3 months, HAE resulted in significantly higher RECIST response. However, after 6 months no difference remained. For the treatment of liver metastases from small intestinal neuroendocrine tumors (SI-NET), results supported the safety profile of HAE.
