What is IGRT?
Image-guided radiation therapy, or IGRT, is a type of cancer treatment that uses imaging technologies such as PET, MRI, and CT to more accurately and safely deliver radiation to cancer cells. The machines that are used to deliver the radiation, called linear accelerators, are equipped with the imaging equipment so that doctors can confirm exactly where the tumor is in the body before and during treatments.

What are the advantages of IGRT?
The main advantage of IGRT is that it is very precise. It makes it possible to
• use higher doses of radiation to kill the cancer
• avoid harm to healthy tissue
• keep radiation side effects to a minimum
