Does the anabolic metabolism of L-[2-18F]fluorophenylalanine and L-[2,6-3H]phenylalanine differ in the cerebrum and the cerebellum?

abstract：INTRODUCTION:Prognostic markers for progression of polycystic kidney disease (PKD) are limited. We evaluated the potential of early para-[(18)F]fluorohippurate ([(18)F]PFH) positron emission tomography (PET) renography to predict future progression of PKD in Han:SPRD rats with slowly progressive autosomal dominant PKD....
