Abstract
A new solid phase method for hydrolysis of acetyl groups from the inte rmediate 2-[F-18]fluoro-2-deoxyglucose tetraacetate ([F-18]FDG-Ac-4) w as developed. Fast cleavage occurs with Dowex 50 sulfonic acid resin ( H+ form) at similar to lOO degrees C in the absence of bulk water. [F- 18]FDG-Ac-4 reaction mixtures were efficiently converted to neutral aq ueous solutions of pure FDG in 10-15 min. The method avoids problems a ssociated with liquid acids and can be easily integrated into existing [F-18]FDG procedures.
