Striatal Dopamine Transporter Binding Assessed by [I-123]IPT and Single Photon Emission Computed Tomography in Patients With Early Parkinson's Disease

Abstract

Use of [I-123] IPT and single photon emission computed tomography demonstrates a reduction of dopamine transporter binding in patients with early Parkinson's disease. Significantly reduced IPT binding already observed in the ipsilateral striatum of patients with Hoehn and Yahr stage I demonstrates the potential of this method to detect preclinical disease.
