How does Image-guided Radiation Therapy work?
Image-guided radiation therapy (IGRT) is the use of imaging during radiation therapy to improve the precision and accuracy of treatment delivery.
IGRT is used when treating tumours in areas of the body that move, such as the lungs. Radiation therapy equipment when used with imaging technology allows the radiographer to image the tumour before and during your treatment. By comparing treatment images to the images taken during treatment planning, the radiation beams may be adjusted to more precisely target the radiation dose to the tumour. To help line up and target the equipment, some IGRT procedures may use ultrasound, MRI, X-Ray images, CT scans, 3-D body surface mapping, or coloured ink markers on the skin.
If you undergo IGRT, your doctor will often use CT scanning to create reference images and to carry out a treatment simulation session. Other imaging procedures, such as a PET or MRI scan, may be used to help clarify the exact shape and location of your tumour, with a special device sometimes being created to help you maintain your exact position during each treatment.
We work together to combine the highest levels of consultant-led care and patient choice with the most advanced knowledge and understanding of the disease and its forms.
Cancers Image-guided Radiation Therapy can treat
Q. Will this treatment hurt?
A. No, administering this treatment won’t cause any pain. However, side-effects from the treatment may cause some discomfort.
Q. How long will the treatment take?
A. This treatment usually only takes a few minutes and is repeated over a set number of sessions based on your condition.
Q. What side effects can I expect?
A. Side effects are unique to each patient; however, they go away once the treatment is complete. Common side effects can include skin reactions and hair loss at the site of treatment, nutritional problems, fatigue, and a reduction in white blood cells.
Q. Will I be radioactive after the treatment?
A. No, once the treatment is complete you won’t be radioactive as the radiation is administered externally. Once complete it’s perfectly safe for you to be around other people.
