| Summary: | Transarterial radioembolization (TARE) is a minimally invasive treatment modality for hepatocellular
carcinoma (HCC) that delivers targeted radiation via radioactive microspheres.
The procedure entails selective catheterization of the hepatic artery, followed by infusion of
yttrium-90-labeled microspheres directly into the arterial supply of the tumor. Several technical
strategies are employed to optimize precise radiation delivery while minimizing exposure
to surrounding healthy liver tissue. Post-procedure imaging is crucial for assessing
therapeutic efficacy. Contrast-enhanced CT or MRI is routinely performed to evaluate tumor
response, which may manifest as reductions in tumor size, decreased vascularity, or increased
necrosis. It is important to recognize that radioembolization-induced changes in
the liver parenchyma can mimic tumor recurrence, which may lead to unnecessary additional
interventions if misinterpreted. Follow-up imaging also plays an essential role in
identifying potential complications, including non-target radiation injury and disease progression.
Overall, TARE has demonstrated promising outcomes in improving survival and
quality of life for patients with HCC, establishing itself as a valuable option within the multidisciplinary
management of liver cancer. |
