abstract = {Purpose To evaluate the ability to detect intracerebral
regions of increased glucose concentration at T1ρ-weighted
dynamic glucose-enhanced (DGE) magnetic resonance (MR)
imaging at 7.0 T. Materials and Methods This prospective
study was approved by the institutional review board. Nine
patients with newly diagnosed glioblastoma and four healthy
volunteers were included in this study from October 2015 to
July 2016. Adiabatically prepared chemical
exchange-sensitive spin-lock imaging was performed with a
7.0-T whole-body unit with a temporal resolution of
approximately 7 seconds, yielding the time-resolved DGE
contrast. T1ρ-weighted DGE MR imaging was performed with
injection of 100 mL of $20\%$ d-glucose via the cubital
vein. Glucose enhancement, given by the relative signal
intensity change at T1ρ-weighted MR imaging (DGEρ), was
quantitatively investigated in brain gray matter versus
white matter of healthy volunteers and in tumor tissue
versus normal-appearing white matter of patients with
glioblastoma. The median signal intensities of the assessed
brain regions were compared by using the Wilcoxon rank-sum
test. Results In healthy volunteers, the median signal
intensity in basal ganglia gray matter (DGEρ = $4.59\%)$
was significantly increased compared with that in white
matter tissue (DGEρ = $0.65\%)$ (P = .028). In patients,
the median signal intensity in the glucose-enhanced tumor
region as displayed on T1ρ-weighted DGE images (DGEρ =
$2.02\%)$ was significantly higher than that in
contralateral normal-appearing white matter (DGEρ =
$0.08\%)$ (P < .0001). Conclusion T1ρ-weighted DGE MR
imaging in healthy volunteers and patients with newly
diagnosed, untreated glioblastoma enabled visualization of
brain glucose physiology and pathophysiologically increased
glucose uptake and may have the potential to provide
information about glucose metabolism in tumor tissue. ©
