Image-Guided Radiation Therapy (IGRT) is an advanced approach to radiation therapy that includes imaging techniques during every treatment session. Radiation therapy makes use of high-energy beams of radiation to regulate cancer and noncancerous cell growth. By adding detailed images, IGRT assures that intense radiation is scarcely focused on the treatment region.
Oncologist uses IGRT to treat all types of cancer, however, it’s specifically suited for curing tumours and cancers located very close to vital organs and sensitive structures. Also, it is beneficial for tumours that are likely to move during treatment or between treatment periods. Some of the features of IGRT radiation therapy include:
Some of the side effects observed after IGRT radiation treatment include:
IGRT treatment session usually takes about 30 minutes in total. The therapist sets up the treatment schedule as per the 3D images of the tumour obtained and the information from the simulation.
Generally, most side effects settle within a few weeks to 2 months of completing the session. But some side effects may persist even after treatment is over, as it takes time for healthy cells to heal and repair from the side effects of radiation therapy.
