Intensity Modulated Radiation Therapy (IMRT) for Brian Cancer
Depending on the type and grade of the tumor and other factors, some brain cancer patients at CTCA receive intensity modulated radiation therapy (IMRT). A type of external beam radiation therapy (EBRT), IMRT allows us to deliver higher radiation doses to brain tumors, while minimizing damage to healthy brain tissue.
With IMRT, our radiation oncologists first use imaging technology to locate tumors in the brain. Then, we use a linear accelerator (a special X-ray machine that moves around the body) to direct pencil-thin radiation beams to the brain tumor, at varying angles and intensity levels.
Because of its accuracy, this technology helps to reduce damage to healthy brain tissue and minimize side effects. As a result, Intensity Modulated Radiation Therapy is particularly useful when treating tumors that are close to critical structures in the brain, such as the brain stem or the nerves of the eyes.
Advantages of Brain Cancer IMRT
- IMRT uses an advanced computer program to plan a precise dose of radiation based on the brain tumor’s size, shape and location.
- IMRT allows our doctors to deliver higher doses of radiation from any angle, and shape radiation beams to match the contour of the brain tumor.
- By adjusting the intensity of the radiation beams across the treatment area with laser accuracy, Intensity Modulated Radiation Therapy helps to spare healthy brain tissues and reduce side effects.
Helping You Maintain Your Quality of Life
Your CTCA care team anticipates and proactively manages the potential side effects of radiation therapy for brain cancer. Before, during and after your brain cancer treatment, you’ll receive supportive therapies designed to keep you strong and nutritionally fortified, reduce the side effects of radiation, and promote your overall well-being.
