La radiothérapie externe guidée par l'imagerie dans le cancer de la prostate ; comment, quand et pourquoi ?

Novel techniques of prostate cancer radiotherapy require increased precision, which is allowed by Image Guided Radiation Therapy (IGRT), using fiducial markers and orthogonal radiographs, cone beam computed tomography, magnetic resonance imaging, ultrasound, and/or transponders. IGRT may reduce the toxicity of radiation therapy, but there is no clear recommendation on the best IGRT technique and how often it should be applied.
