FIGURE 1.

Representative ROI delineations. A 53-year-old man was diagnosed with glioblastoma, IDH-wildtype. (A) contrastenhanced T1-weighted image (T1WI-CE); (B) the time-signal intensity curve; (C) the transfer constant (ktrans) image; (D) rate constant (kep) image; (E) extravascular extracellular volume fraction (ve) image; (F) initial area under the curve in the first 60 s (iauc) image. On images, B-F, ROI 1 marked green represented tumor parenchyma, ROI 2 marked yellow represented the peripheral zones, and ROI 3 marked blue-turquoise represented contralateral normal-appearing brain tissues.

FIGURE 3.

Some representative MRI images without imaging necrosis which was exactly confused in diagnosing imaging necrosis. Shown from left to right by the order are T1WI, T2WI, and T1WI-CE. (A) a 24-year-old man with an oligodendroglioma, IDH-mutant and 1p/19q-deleted, CNS WHO grade 2; (B) a 39-year-old man with an oligodendroglioma, IDH-mutant and 1p/19q-deleted, CNS WHO grade 2; (C) a 55-year-old woman with an oligodendroglioma, IDHmutant and 1p/19q-deleted, CNS WHO grade 2; (D) a 45-year-old man with an astrocytoma, CNS IDH-mutant, WHO grade 2; (E) a 36-year-old woman with an oligodendroglioma, IDH-mutant and 1p/19q-deleted, CNS WHO grade 2. In this case (E), it showed multiple long tubular and filiform enhancement and there were some tumor areas with remarked decrease of reinforcement. But these areas are hyperintense, not hypointense, on the T1-weighted image. Comparing with CT images (not provided), calcification on these areas were just observed. So, there was no imaging necrosis in these conditions.
