Image-Guided Radiotherapy (IGRT)
Image-guided radiation therapy (sometimes called image-guided adaptive radiation therapy or IGART) is a method of disease management that uses advanced imaging technology to monitor your treatment throughout the entire treatment process.
In traditional radiation treatment, your disease is diagnosed, staged, and imaged at the beginning of treatment, and the information is used to plan treatment for the whole of the course.
Thanks to the advances in imaging, doctors now know that your anatomy and the tumor's size and shape can change during treatment.
As such, plans made early on may not be appropriate for the entire course of treatment.
Benefits of IGRT
IGRT uses advances in imaging to track these changes through all stages of treatment.
By re-imaging and modifying your treatment plan at key points, radiation oncologists are able to respond as the disease reacts to the therapy.
This can result in:
- Better treatment
- More precise and effective radiation therapy
- Fewer side effects
