图2. 部分T2/FLAIR错配征的ROI勾画,左侧颞顶岛叶少突胶质细胞瘤IDHMUT/1p/19q?,WHO Ⅱ级.(a)轴位T2WI,病变呈混杂信号,边界欠清,周围脑组织见少许水肿.瘤体部分区域呈高信号;(b)轴位FLAIR,病变以混杂信号为主.部分区域呈相对低信号(除外明显囊变、坏死及水肿);(c)轴位T1增强,错配区域病变未见明显强化

Fig.2. The ROI of the T2/FLAIR mismatch sign in part of the tumor. The left temporal parietal insula oligodendroglioma with IDHMUT/1p/19q?, WHO grade Ⅱ. (a) Axial T2WI, the lesion showed mixed signals, the boundary was not clear, and there was a little edema in the surrounding brain tissue, some areas of the tumor showed high signal; (b) Axial FLAIR, the lesions are dominated by confounding signals. Some areas of the tumor showed relatively lower signal (except for obvious cystic degeneration, necrosis and edema); (c) Axial T1 enhancement, no obvious enhancement of the lesion in the mismatched area
