摘　　要：随着放疗技术的发展，MRI在颅内恶性胶质瘤放射治疗中的应用越来越广泛，尤其是在颅内恶性胶质瘤的预后判断、放疗定位与靶区勾画、肿瘤复发与坏死鉴别等方面。在放疗计划方面，由于MRI具有优越的软组织分辨能力，因此已广泛用于靶区勾画中，目前多采用与cT融合进行靶区勾画，而完全采用MRI进行定位及靶区勾画的研究方兴未艾。在肿瘤复发与坏死鉴别方面，随着功能性成像的发展，MRI正发挥着越来越大的作用，已成为必不可少的一种检查手段。MRI was used in radiotherapy of brain tumor more and more comprehensively, especially in the prognosis, radiotherapy planning and differentiation between recurrence and necrosis of brain tumor. Due to the excellent ability in the differentiation of soft tissue, MRI extensively fusing with CT was used in drawing the outline of the tumor. Maybe in the future, it is possible to use MRI absolutely in radiotherapy planning of brain tumor. With the development of the functional MRI, MRI will be a necessary method used widel） in the differetion between brain tumor reccurence and radiation injury.
