Can we ablate liver lesions close to large portal and hepatic veins with MR-guided HIFU? An experimental study in a porcine model

ConclusionsAblations yielding coagulative necrosis of liver tissue can be performed adjacent to large hepatic vessels while keeping the vessel walls intact. This indicates that perivascular tumor ablation in the liver is feasible using MRgHIFU.Key Points•High-intensity focused ultrasound ablation is a non-invasive treatment modality that can be used for treatment of liver tumors.•This study shows that ablations of liver tissue can be performed adjacent to large hepatic vessels in an experimental setting.•Liver tumors close to large vessels can potentially be treated using this modality.
