Does radiation damage your liver?
Abstract. Radiation-induced liver disease (RILD) or radiation hepatitis is a sub-acute form of liver injury due to radiation. It is one of the most dreaded complications of radiation which prevents radiation dose escalation and re-irradiation for hepatobiliary or upper gastrointestinal malignancies.
How is liver radiation done?
X-rays are used to thread the catheter up into the big artery in your liver (hepatic artery). Then the doctor pushes tiny radioactive beads through the catheter and into the artery. Blood flow carries the beads into the liver near tumors and they get stuck in the small arteries there.

What is intensity modulated radiation therapy?
Intensity modulated radiation therapy (IMRT) uses software to plan a precise dose of radiation, based on tumor size, shape and location. Compared to standard radiotherapy, IMRT allows a radiation oncologist to use higher radiation doses than traditional therapies would allow in these areas. At the same time, IMRT helps to spare more of the surrounding healthy liver tissue from harmful doses of radiation.
What is EBRT in medical terms?
External beam radiation therapy (EBRT) delivers high-energy radiation to tumors using a special X-ray machine called a linear accelerator. This machine allows radiation to be delivered from any angle and shapes radiation beams to the contour of the tumor. EBRT is an outpatient procedure. The procedure itself is painless and poses no risk of radioactivity to you or others with whom you have contact. As you undergo EBRT, you may continue normal activities with family and friends.
Why does the liver move during radiation?
