Values are reported as median (interquartile range); wild, isocitrate dehydrogenase (IDH) wild-type without 1p/19q-codeleted; mut, IDH mutant without 1p/19q-codeleted; codel, IDH mutant with 1p/19q-codeleted; TNR, tumor-to-normal ratio; MTV, metabolic tumor volume; TLMU, total legion methionine uptake; LGRE, low gray-level run emphasis; HGRE, high gray-level run emphasis; GLNUr, gray-level non-uniformity for run.
