Differentiation between solitary metastatic lesions and glioblastomas, two of the most common malignant brain neoplasms, is often a diagnostic challenge. The purpose of this review is to emphasize the potential roles of advanced magnetic resonance imaging (MRI) techniques, including diffusion-based techniques, such as diffusion-weighted imaging (DWI), exponential DWI, and diffusion tensor imaging, MR perfusion, and MR spectroscopy, as well as conventional MRI, in making a distinction between glioblastomas and solitary metastases in peritumoural regions. Integration of advanced MRI features with conventional MRI, may provide valuable information for differentiating glioblastoma from solitary metastatic lesions.
鉴别单发转移瘤和胶质母细胞瘤（GBM），这两种是最常见的恶性脑肿瘤，往往具有挑战性。本综述旨在强调高级磁共振成像（MRI）技术的潜在作用，包括基于弥散的技术，如弥散加权成像（DWI）、指数 DWI 和弥散张量成像，MR 灌注和磁共振波谱，以及常规 MRI，在区分肿瘤周围区域的 GBM 和单发转移瘤方面。高级 MRI 特征与常规 MRI 的结合，可能为鉴别胶质母细胞瘤和单发转移瘤提供有价值的信息。
