The present invention provides positron emitter radiolabeled versions of PABA, metabolites and derivatives, with good radiochemical yield, high specific activity, high chemical and radiochemical purity and having excellent characteristics for PET imaging. The inventive composition and methods provide high quality dynamic images of the kidneys while reducing the radiation exposure. The short biological half-life of PABA, added to the short physical half-life of positron emitters such as 11C will also benefit patients that require multiple renography assessments in a short period of time.
