Brief Summary:
This study assesses dopamine transporter density using single photon emission computed tomography (SPECT) brain imaging with an investigational radiopharmaceutical, [123I]ß-CIT, in research participants with Parkinson's disease.

Condition or disease Intervention/treatment Phase
Parkinson's Disease Parkinsonian Syndrome Procedure: [123I]ß-CIT and SPECT imaging Phase 2

Detailed Description:

The brain imaging is conducted at the Institute for Neurodegenerative Disorders in New Haven, Connecticut. The imaging procedure occurs over a two day period.

After a screening visit, including review of the potential subject's neurological history and a thorough neurologic exam, subjects are injected with [123I]ß CIT, an investigational radioactive material that localizes in the brain.

Twenty-four hours later study participants return to the Institute for Neurodegenerative Disorders where an investigational scanning procedure is used to obtain SPECT (single photon emission computed tomography) images of the brain.

Primary Outcome Measures :
  1. CIT uptake: measurement of dopamine transporter density compared with the clinical severity of illness

Secondary Outcome Measures :
  1. Measurement of variability of strital uptake of [123I]ß-CIT when more than one scan has occurred
