NCT00129675

Brief Summary

The overall goal of this study is to evaluate the use of dopamine transporter (DAT) imaging as a diagnostic tool in subjects with early parkinsonian symptoms, in whom Parkinson's disease (PD) or parkinsonian syndrome (PS) is suspected, but the diagnosis remains unclear from a clinical standpoint.

Outcome Measures

Primary Outcomes (1)

  • Comparison of the imaging diagnosis, based on visual analysis and quantitative analysis, to the clinical diagnosis of the investigator blinded to the imaging results

    5 years

Secondary Outcomes (1)

  • Comparison of the DAT imaging diagnosis, initial diagnosis by the movement disorder experts and referral neurologist diagnosis to the 'gold standard' diagnosis

    5 years

Study Arms (1)

[123I]ß CIT

EXPERIMENTAL

To assess \[123I\]ß CIT and SPECT imaging

Drug: [123I]ß CIT

Interventions

Single Photon Emission Computed Tomography SPECT imaging uses the single photon emissions from radioactive compounds that are (most commonly) injected into a patient and are metabolized by specific organs or body systems. SPECT imaging is performed by using a gamma camera to acquire multiple 2-D images (also called projections), from multiple angles. A computer is then used to apply a tomographic reconstruction algorithm to the multiple projections, yielding a 3-D dataset. This dataset may then be manipulated to show thin slices along any chosen axis of the body, similar to those obtained from other tomographic techniques, such as MRI, CT, and PET. The resulting SPECT images reflect body/organ function as opposed to specific anatomy of other imaging modalities such as CT or MRI.
