目前,MRI因软组织分辨率高、无辐射及多平面成像等优势已成为脑肿瘤疾病的一种常规检查手段。近年来,随着磁共振技术的发展及磁场强度的增加,一些新的MR功能成像技术已开始越来越多的应用于临床,如磁共振波谱、脑功能成像、灌注成像、磁敏感加权成像、弥散张量成像等,主要用于脑肿瘤之间及脑肿瘤与非肿瘤性疾病的鉴别、肿瘤的分级、指导外科术式的选择、放疗方案的制订等。 Currently, MRI has become a routine test for brain tumor diseases due to the advantages of high resolution of soft tissue, non-radiation and multi-planar imaging. In recent years, with the development of magnetic resonance technology and the increase of magnetic field strength, some new MR functional imaging technologies have been increasingly used in clinical applications such as magnetic resonance spectroscopy, brain imaging, perfusion imaging, magnetic susceptibility weighted imaging , Diffuse tensor imaging, etc., mainly for brain tumors and between brain tumors and non-neoplastic disease identification, classification of tumors, surgical guidance to guide the choice of the formulation of radiotherapy programs.
