摘要

A diagnostic agent for glycometabolic function comprising a glucose derivative of the formula (I): wherein R1, R2, R3 and R4 are the same or different and each represents hydrogen or acyl having 2 to 8 carbon atoms, with the proviso that at least one of R1, R2, R3 and R4 is acyl and R5 represents X or -NHCOR6X wherein X is a radioisotope of halogen and R6 is arylene or alkylene having 1 to 3 carbon atoms.
