Radioembolization is an extremely valuable interventional oncology tool in treatment of primary and metastic hepatic malignancy. This procedure allows interventional radiologists to target liver tumors with lethal radiation dose while minimizing normal hepatic parenchymal exposure. In most patients, this is extremely well-tolerated and can be performed as an outpatient. Non-target embolization (radiation-induced lung, liver, or bowel injury) is a rare, but potentially serious and life-threatening complication. It is important for radiologists to understand critical information about the procedure, including patient selection, mechanism of action, risks, and imaging that routinely is obtained before and after the procedure.

Presentation will be in quiz format. Major teaching points about indications and contraindications of radioembolization will be reviewed. Differences between the two radioembolization products will be covered. Eight cases will be utilized to cover this points as well as highlight outcomes from major research studies. Cases will include: -Primary liver tumors -Metastatic disease to the liver -Highlight normal anatomy as well as key anatomical variants -Importance of mapping angiography and nuclear medicine scintigraphy -Adjunctive techniques that may aid in uptake of dose into the tumors and/or improve safety.
