MGMT and neoplasm: Necrosis, tumor mass, and FLAIR-T2 volumes in non-methylated MGMT tumors were larger than in methylated MGMT tumors: 18.7 vs. 10.7 cm3, 33.9 vs. 23.3 cm3, and 104.3 vs. 82.1 cm3, respectively, without statistical significance (Mann–Whitney U-test p = 0.161, 0.204, and 0.195, respectively).
