Study of Individuals With Parkinson's Symptoms But in Whom There is Diagnostic Uncertainty
Development of a Imaging Marker for Parkinson's Disease Through Use of Dynamic SPECT Imaging With [123I] Beta-CIT in Individuals With Parkinson's Symptoms
Study Overview
Detailed Description
- Subjects will be referred to the Institute for Neurodegenerative Disorders (IND) by practicing general neurologists with genuine uncertainty regarding the subject's diagnosis.
- Subjects with suspected PD or PS will be evaluated clinically and with DAT imaging, using b-CIT and SPECT. The DAT imaging procedure will take place over two days:
- On the first day participants are injected with [123I]ß CIT, an investigational radioactive material that localizes in the brain. Study participants will also have a thorough neurologic examination and standard neuropsychological testing, including testing of memory, concentration, abstraction and visual spatial functions.
- Twenty-four hours later study participants return to the Institute for Neurodegenerative Disorders where an investigational scanning procedure will be used to obtain SPECT (single photon emission computed tomography) images of the brain.
- Subjects will be asked to return within 3 months following the imaging study to have a repeat neurological examination by the two study neurologists at IND.
- Subjects will be asked to return at about 6 months and possibly again at one year following the imaging study for a final clinical evaluation by one of the study neurologists at IND.

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.
