Invivo MR anatomy, diffusion, perfusion, and
spectroscopy profiles from non-enhancing grade 2 and grade 3 gliomas were
examined by histologic and molecular characteristics associated with clinical
outcome. Patients underwent a pre-surgical 3T MR exam including IRSPGR, FSE, FLAIR,
DWI, MRSI and DSC. For surgical biopsies, histological sub-type, grade, cleaved
caspase-3, MIB-1, Ki67, IDH1R132H, ATRX, p53, and co-deletion of 1p19q were
determined. Overall, molecular characteristics associated with worse clinical
outcome were associated with higher ADC and lower FA, lower nCBV and nPH, and
higher Recov, and higher nLAC.
