Glucose metabolism

Glucose metabolism is difficult to image with cellular resolution in mammalian brain tissue, particularly with 18fluorodeoxy-D-glucose (FDG) positron emission to- mography (PET). To this end, we explored the potential of synchrotron-based low-energy X-ray fluorescence (LEXRF) to image the stable isotope of fluorine (F) in phosphorylated FDG (DG-6P).

In our study, we used synchrotron soft X-ray imaging and X-Ray Fluorescence (XRF) microscopy to study glucose uptake in retina and brain tissues at 1 um2 spatial resolution in 3 um-thick brain slices. This study demonstrates the ability to identify glucose uptake at subcellular resolution and holds remarkable potential for imaging glucose metabolism in biological tissue.
