Three-dimensional conformal radiation therapy (3D-CRT)
Three-dimensional conformal radiation therapy, or 3D-CRT, uses computers and special imaging techniques such as PET, MRI, or CT scanning to reveal the size, shape and location of the tumour.Contact Us
How does Three-dimensional conformal radiation therapy (3D-CRT) work?
Because tumours are not all the same, i.e. they come in all shapes and sizes, three-dimensional conformal radiation therapy, or 3D-CRT, uses computers and special imaging techniques such as PET, MRI, or CT scanning to reveal the size, shape and location of the tumour as well as adjacent organs, with a radiation treatment plan then tailored specifically to every patient’s anatomy.
At the beginning of the planning stage, a radiographer will perform a CT scan of the part of the body being treated. These images are then loaded into a computer specific to the purpose and used to devise a radiation treatment plan. The plan is to enable your radiation oncologist to deliver with precision, a beam of radiation that conforms closely to the shape, size and contour of the tumour. Because the radiation beams are directed very precisely, nearby normal tissue receives less radiation than cancerous tissue and is therefore able to heal more quickly.
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 Three-dimensional conformal radiation therapy (3D-CRT) 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. Radiation therapy 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.
