Trial Outcomes & Findings for A Study to Assess Changes in Clinical Management After DaTSCAN Imaging of Subjects With Clinically Uncertain Parkinsonism or an Illness With Similar Symptoms (NCT NCT00382967)

NCT ID: NCT00382967

Last Updated: 2012-09-03

Results Overview

The impact the Datscan image had on the Doctor's decisions on the clinical management of subjects. A record of the number of changes in the Doctor's clinical management. It is possible for a subject to have multiple changes in Clinical management and other subjects to have no change in their management.

SECONDARY outcome

Timeframe: From the first patient Visit 1 (1 month) to Visit 4 (12 months). This goes from the baseline (visit 1) up to 1 year post contrast administration.

Population: The numbers represent the number of changes in decisions that the Doctor made in the clinical management of the patient with Clinically Uncertain Parkinsonism

The impact the Datscan image had on the Doctor's decisions on the clinical management of subjects. A record of the number of changes in the Doctor's clinical management. From the first patient visit (baseline) to the fourth patient visit, which was 12 months. This was a 1 year time period being assessed.It is possible for a subject to have multiple changes in Clinical management and other subjects to have no change in their management.
