Tumor cell irradiation by beta-emitting yttrium-90 microsphere deposition in hepatic vasculature (Y-90 Radioembolization)

This procedure involves the deposition of beta-emitting yttrium-90 microspheres into the hepatic vasculature to irradiate tumor cells. It is a minimally invasive treatment that combines embolization with radiation therapy to target liver tumors, particularly for inoperable cases. The microspheres emit radiation over a short period, leading to tumor cell death while minimizing damage to surrounding healthy tissue.

Delivery of beta radiation directly to tumors via microspheres. Blocking blood supply to tumors. Inducing cell death in tumor cells while sparing healthy tissue.
