Differentiation between glioblastoma multiforme (GBM) and solitary brain metastasis (SBM) remains a challenge in neuroradiology with up to 40% of the cases to be incorrectly classified using only conventional MRI. The inclusion of perfusion MRI parameters provides characteristic features that could support the distinction of these pathological entities. On these grounds, we aim to use a perfusion gradient in the peritumoral edema.

胶质母细胞瘤与孤立性脑转移：使用水肿灌注梯度进行 MRI 鉴别

区分多形性胶质母细胞瘤 (GBM) 和孤立性脑转移瘤 (SBM) 仍然是神经放射学中的一个挑战，多达 40% 的病例仅使用常规 MRI 就被错误分类。灌注 MRI 参数的包含提供了可以支持区分这些病理实体的特征。基于这些理由，我们的目标是在瘤周水肿中使用灌注梯度。
