Abstract

The amino acid PET tracer L3,4-dihydroxy-6-[18F]fluoro-L-phenylalanine (FDOPA), a radiolabeled analog of L-DOPA, is indicated for the molecular imaging of metabolic abnormalities of presynaptic dopamine transporters and L-type amino acid transporters. In clinical neurology, FDOPA-PET assesses the brain’s dopaminergic function for diagnosing Parkinson’s disease (PD) and differentiation between essential tremor and parkinsonian syndromes. In neuro-oncology, FDOPA-PET uptake measures the rate of L-type amino acid transport activity, given that malignant brain tumors are linked to increased protein synthesis and amino acid transport, resulting in higher uptake than normal tissue. FDOPA-PET is increasingly being used to complement MRI in diagnosing and managing patients with brain tumors, especially gliomas.
