Purpose
The primary objective of this study is to determine if the diagnostic performance of DaTscan™ single photon emission computed tomography (SPECT) imaging is different in non-Caucasian subjects compared with Caucasian subjects with movement disorders.

Primary Outcome Measures:
- Blinded visual assessment of each subject's DaTscan image as normal or abnormal [ Time Frame: 1 day ] [ Designated as safety issue: No ]Blinded visual assessment of each subject's DaTscan™ image as normal or abnormal by majority interpretation in the Blinded Image Evaluation (BIE).
Secondary Outcome Measures:
- Abnormal images categorized [ Time Frame: 1 day ] [ Designated as safety issue: No ]Abnormal images will be further categorized as 1) abnormal and typical of PD, or 2) abnormal but atypical of PD.

| Groups/Cohorts | Assigned Interventions |
|---|---|
|
Non-Caucasian
Non-Caucasian male and female adult subjects (greater than or equal to 18 years of age) with an initial diagnosis of suspected PD or ET who underwent DaTscan SPECT imaging to assist with the subject's final clinical diagnosis of PD or ET.
|
Other: Subjects dosed in a separate study
The subjects in this study were dosed with DaTscan drug product in a separate study.
|
|
Caucasian
Caucasian male and female adult subjects (greater than or equal to 18 years of age) with an initial diagnosis of suspected PD or ET who underwent DaTscan SPECT imaging to assist with the subject's final clinical diagnosis of PD or ET.

Criteria
Inclusion Criteria:
For Non-Caucasians:
- Non-Caucasian male and female adult subjects (greater than or equal to 18 years of age) with an initial diagnosis of suspected PD or ET who underwent DaTscan SPECT imaging to assist with the subject's final clinical diagnosis of PD or ET.
- The subject has existing diagnostic-quality and interpretable DaTscan SPECT images of the brain.
For Caucasians:
- Caucasian male and female adult subjects (greater than or equal to 18 years of age) with an initial diagnosis of suspected PD or ET who underwent DaTscan SPECT imaging to assist with the subject's final clinical diagnosis of PD or ET.
- The subject has existing diagnostic-quality and interpretable DaTscan SPECT images of the brain.
- The subject is matched by final clinical diagnosis, sex and age (±5 years) with a non-Caucasian subject.
Exclusion Criteria:
- Known/suspected structural abnormalities of the brain (e.g., hydrocephalus; brain tumor; stroke; etc.) that can grossly distort the DaTscan images.
