Administering selective internal radiation therapy using microspheres containing yttrium-90, known as macroaggregated albumin (MAA), directly into the blood supply of liver tumors results in tumor necrosis. The microspheres are designed to lodge in small blood vessels within the tumor, delivering targeted radiation that leads to cell death and necrosis of the tumor tissue. This treatment is particularly effective for patients with primary liver malignancies such as hepatocellular carcinoma or metastatic liver disease.

The process works by effectively reducing the tumor's viability and can lead to improved outcomes in patients, including reduced tumor size over time, although this might not be immediate. This mechanism of action is a key reason for the use of MAA in interventional radiology as part of a treatment plan for liver tumors.
