胶质瘤(gliomas)是一类起源于神经胶质细胞和神经干细胞最常见的脑内肿瘤,占脑恶性肿瘤中80%[1]。依据肿瘤恶性程度WHO将其分为4级,2016年5月WHO又发布新的脑肿瘤分级标准,引入了胶质瘤相关特征分子作为重要的病理分型指标[2]。磁共振成像技术不仅可以提供脑肿瘤的解剖结构以及病理特征信息,在一定程度上也能够反映胶质瘤的某些分子表型特征[3]。在临床应用方面,MRI已能够对 Gliomas are a group of the most common intracerebral tumors that originate in glial cells and neural stem cells, accounting for 80% of brain malignancies [1]. According to the degree of tumor malignancy WHO will be divided into four, in May 2016 WHO has released a new classification of brain tumors, the introduction of glioma-related molecules as an important indicator of pathological classification [2]. Magnetic resonance imaging can not only provide information on the anatomical structure of brain tumors and pathological features, but also reflect certain molecular phenotypic features of glioma to some extent [3]. In clinical applications, MRI has been able to
