摘要使用MRI代替CBCT进行IGRT,不但利用了MRI特有的影像学优势,还可以在线和实时跟踪肿瘤运动和生物学变化,实现解剖学与生物学上"真正"的实时MRI引导ART,是放疗史上又一个里程碑式的技术进步.本文就MRI引导放疗的技术优势、MR-Linac的基本构造和类型、MRIgART的技术难题和解决措施进行综述.

abstractsCone-beam computed tomography (CBCT)-guided radiotherapy has been widely used in radiotherapy, but it still has many limitations.Using magnetic resonance imaging (MRI) instead of CBCT for imaging-guided radiotherapy can not only make use of the advantages of MRI, but it also allows for online and real-time tracking of tumor motion and biological changes.This technique truly realizes the real-time MRI-guided adaptive radiotherapy (ART) in anatomy and biology, and sets another milestone in the advancement of radiotherapy.This review summarizes the technical advantages of MRI-guided radiotherapy, the basic structure and type of MR-Linac, and the technical difficulties and solutions of MRIgART.
