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.
What is the second session of radiation?
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.
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.
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.
Why do you have to embolize your liver?
At this time, any arteries passing from the liver circulation to non-target structures , such as the stomach or bowel, can be embolized ( blocked off) with coils, to prevent radiation damage to these organs. A test will also be done to confirm that there is not shunting of blood flow through the liver into the lungs.

Where are Y-90 microspheres injected?
With the Y-90 radioembolization treatment, the microspheres are injected through a catheter from the groin into the liver artery supplying the tumor. The beads become lodged within the tumor vessels where they exert their local radiation that causes cell death.
Why are liver tumors inoperable?
Liver tumors are often inoperable because the tumors may be too large or numerous or have grown into major blood vessels or other vital structures. Historically, chemotherapy drugs become less effective as the disease progresses," he added.
Why did the Nuclear Regulatory Commission change its guidelines?
