This research aims to quantify brain deuterium metabolism using 7T imaging in healthy individuals and glioblastoma patients.
Utilized 7T MRI for brain deuterium metabolic imaging (DMI)
Compared metabolic profiles between glioblastoma patients and healthy volunteers
Analyzed lactate (Lac) and glutamate/glutamine (Glx) levels
Glioblastoma tumors exhibited increased Lac levels compared to normal brain.
Reduced Glx labeling was observed in glioblastoma patients.
Inter-patient metabolic heterogeneity suggests different glioblastoma subtypes.

Implication

Absolute quantification shows metabolic alterations in glioblastoma, indicating distinct subtypes exist.

Abstract

We demonstrate robust absolute quantification for human 7T DMI. Glioblastoma tumors showed elevated Lac and reduced Glx labeling relative to normal brain, with inter-patient heterogeneity consistent with an existence of different metabolic subtypes.
