Abstract
Commonly utilized treatments for primary, secondary, and recurrent cancers of the liver include resection, radiofrequency ablation, percutaneous ethanol injection, transarterial chemoembolization, selective internal radiation therapy, and stereotactic body radiation therapy. Image-guided brachyablation represents another solution for treatment of these lesions with good outcomes. With computed tomography, ultrasound, or MRI guidance, interstitial catheters can be introduced percutaneously into the targeted lesions, allowing the subsequent delivery of ablative doses with sparing of other portions of the liver. In this chapter, we provide a brief overview of the evidence behind interstitial liver brachytherapy and outline a method for performing image-guided brachyablation for liver tumors.
