In preclinical research, there is an increasing demand for in vivo imaging techniques to apply to animal models. Here, we report the first protocol for dopamine transporter (DAT) SPECT in common marmosets using the radioligand I-123-N-omega-fluoropropyl-2 beta-carbomethoxy-3 beta-{4-iodophenyl}nortropane (I-123-FP-CIT). Serial SPECT images were obtained on an upgraded clinical scanner to determine the distribution kinetics of I-123-FP-CIT in the marmoset brain. After intravenous injection of approximately 60 MBq of the radiotracer I-123-FP-CIT, stable and specific striatal uptake was observed for at least 4 h. Analysis of plasma samples showed rapid disappearance of the radiotracer from blood plasma within a few minutes after application, with activity declining to 4.1% of the administered activity. Structural magnetic resonance imaging (MRI) at 400 mu m resolution provided the details of the underlying anatomy. In a marmoset model of Parkinson's disease, which was generated by unilateral injections of 6-hydroxydopamine (6-OHDA) into the nigro-striatal projection pathway, complete loss of striatal DAT binding in combination with behavioral deficits was observed. The presented study demonstrates that I-123-FP-CIT SPECT is a suitable tool to investigate DAT integrity in preclinical studies on common marmosets. (C) 2012 Elsevier B.V.
