Abstract:
Two cases of F-FDG PET in developmental venous anomaly (DVA) with visual impairment were examined. Plain MRI could not determine the cause of visual symptoms; a contrast-enhanced CT scan showed the existence of DVA without apparent parenchymal damage due to infarction or hemorrhage. F-FDG PET revealed that the hypometabolic area extended to the visual tract, thus explaining the association between the visual impairment and DVA. F-FDG PET is therefore a useful tool for the evaluation of symptomatic DVA.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
