Magnetic resonance imaging (MRI)-guided radiation therapy is an oncology treatment modality that uses real-time MRI to guide the irradiation of cancerous tissues. This novel type of treatment was developed in the mid-2000s to improve the precision of radiation therapy.
The Direction québécoise de cancérologie asked the Institut national d’excellence en santé et en services sociaux (INESSS) to examine the advisability and efficacy of treating tumours with real-time MRI-guided radiation therapy.
A few simulation studies have examined the feasibility of this technology, but for now, none of them have looked at the efficacy of this treatment. Lastly, because of the lack of efficacy evidence for this technology, no conclusion can be drawn regarding this aspect at this time. Therefore, we cannot, at this point in time, assess the cost, cost-benefit ratio or the number of patients who might benefit from this technology.
