The concept of image-guided radiotherapy benefits from the development of magnetic resonance imaging (MRI) associated with different capacities of tissue analyses such as spectroscopy or diffusion analysis. The production of devices allowing the repositioning of patients through MRI represents a strong added value without delivering any additional dose to the patient while the optimization of the adaptative strategies are facilitated by a better contrast of the soft tissues compared to the scanner. The advantages of MRI are well demonstrated for brain tumours, head and neck carcinomas, pelvic tumors, mediastinal malignancies, gastrointestinal tract diseases. Adaptative radiotherapy inaugurates a new area of radiotherapy with different modalities. Several technological solutions are provided or discussed allowing the patients to benefit from thses new technologies as soon as possible.
图像引导放射治疗的概念得益于磁共振成像（MRI）的发展，它具备诸如光谱分析或扩散分析等不同的组织分析能力。能够通过MRI对患者进行重新定位的设备的生产具有很大的附加价值，同时不会给患者额外增加任何剂量，而且与扫描仪相比，软组织对比度的提高有助于促进自适应策略的优化。MRI的优势在脑肿瘤、头颈部癌、盆腔肿瘤、纵隔恶性肿瘤、胃肠道疾病中得到了充分证明。自适应放射治疗开创了放射治疗的一个新领域，有不同的模式。提供或讨论了几种技术解决方案，以便让患者尽快受益于这些新技术。
