Altered perfusion and uptake of glucose are hallmarks of
tumors and there is a need for MRI methods revealing
tumor perfusion, permeability and aggressiveness. We
employed chemical exchange saturation transfer (CEST)
MRI to dynamically study the delivery and uptake of
D-glucose in an orthotopic glioblastoma model and
compared this with dynamic contrast enhanced (DCE) MRI
with GdDTPA. Dynamic Glucose Enhanced (DGE) data showed
a prolonged uptake of glucose in tumors as compared to
normal brain tissue, and compared well to DCE in
identifying the tumor. The results indicate the
feasibility for using D-glucose as an MRI perfusion
agent for tumor assessment. #Both authors contributed
