TL;DR
Arterio-venous studies in rats showed that DG (and FDG) cannot be used to measure glucose uptake and/or metabolism.
Abstract
Experimental evidence indicated that: 1) [14C]deoxyglucose-6-phosphate (14C-DG-6-P) in brain (and other rat tissues) did not increase with time after injection of 14C-DG, 2) 14C-DG-6-P in rat brain (and other tissues) did not correlate with glucose metabolism, 3) 14C-DG-6-P in rat brain (and other tissues) had a significant negative correlation with glucose-6-phosphatase activity. Further, arterio-venous studies in rats, in which the cerebral uptake and metabolism of labeled glucose were compared directly with those of labeled DG (and labeled fluorodeoxyglucose, FDG), employing double labeled techniques, showed that DG (and FDG) cannot be used to measure glucose uptake and/or metabolism.

The data indicate that cerebral FDG‐6‐PO4 in humans increases for about 90 minutes, plateaus, and then slowly decreases, and that cerebral blood FDG activity levels were found to be a minor fraction of tissue activity.

A mathematical model and derived operational equation are used which enable local cerebral glucose consumption to be calculated in terms of the following measurable variables: gray matter, white matter, and whole brain metabolic rates, calculated as a weighted average based on the approximate volume of each structure.

The rate constants of FDG in man were found to be comparable to those of deoxyglucose in rat and in rhesus monkey and the subject-to-subject variation of LCMRGlc as measured by the present method was comparable to that of other methods that measure whole-brain CMRglc.

The rapid excretion of F-18-DG from liver, lungs and kidneys, and the retention by the heart and brain, is the result of metabolic trapping within certain organs and is reflective of glucose utilization.

Its use for quantitative determination of the rate of rat brain glucose utilization is much more complex than previously realized since deoxyglucose phosphate is lost from brain at an appreciable rate and the ratio of labeled deoxy glucose to blood ratio increases as time passes.

The results call for a reappraisal of the previous biochemical evidence, which negates the existence of brain G-6-Pase, and consequently a reassessment of current concepts pertaining to the metabolic regulation of brain glucose.
