The second session is the delivery of the radiation into the liver cancer. The radiation is in the form of a radioactive isotope called Yttrium-90 or Y-90, which is fixed onto tiny glass or resin particles.
Why is radiation limited in cancer?
External beam radiation is limited because the radiation has to pass through the skin and body wall to reach the targeted cancer, with resultant limitations on dose to avoid damage to surrounding structures.
How many sessions of radioembolization?
How it’s done: Radioembolization requires at least two treatment sessions. The first session is a mapping angiogram, where a catheter is passed into the liver artery from the groin and angiography is used to “map out” all the arteries in the liver circulation.
How does radioembolization work?
Radioembolization allows for internal delivery of radiation through the arteries supplying the cancer, thereby allowing concentration of high doses of radiation in the cancer with minimal effect on the surrounding healthy tissues.
What You Can Expect After the Y-90 Procedure
