TERT and central nervous system cancer: <h4>Objective</h4>To evaluate whether 7-T susceptibility-weighted imaging (SWI) can predict glioma's histological grade, Ki-67 labeling index (LI), isocitrate dehydrogenase 1 (IDH1) mutation, 1p/19q co-deletion, telomerase reverse transcriptase (TERT) promoter mutation, and O-6-methylguanine-DNA-methyltransferase (MGMT) promoter methylation status of gliomas.<h4>Materials and methods</h4>We retrospectively analyzed 7-T SWI in 60 patients with glioma.
