Image-Guided Radiation Therapy (IGRT)

Image-Guided Radiation Therapy (IGRT)


As experts in the use of the latest therapies, including image-guided radiation therapy (IGRT) to treat cancer.  In IGRT, repeated imaging scans such as CT, MRI, or PET are performed during treatment. These imaging scans are processed by computers to identify changes in a tumor’s size and location due to treatment and to allow the position of the patient or the planned radiation dose to be adjusted during treatment as needed. Repeated imaging can increase the accuracy of radiation treatment and may allow reductions in the planned volume of tissue to be treated, thereby decreasing the total radiation dose to normal tissue.  IGRT is often used to treat breast cancer, prostate cancer, lung cancer, gastrointestinal cancer, and head & neck cancer.

Advantages to Patients

The two most beneficial advantages to IGRT therapy include:

  • Fewer side effects due to a more precise radiation doses being delivered to tumors to targeted sites.
  • Reduced treatment toxicity
