Experience with DaTscan at a tertiary referral center

Area of Science:

• Neurology
• Radiology
• Nuclear Medicine

Background:

• Accurate Parkinson's disease diagnosis is challenging, with misdiagnosis leading to inappropriate treatments.
• Dopamine transporter (DaT) imaging assesses striatal dopaminergic integrity, a marker for neurodegeneration.
• A normal DaT scan can suggest alternative diagnoses like essential tremor or drug-induced parkinsonism.

Purpose of the Study:

• To evaluate the impact of DaT imaging on diagnosing and managing parkinsonian syndromes with uncertain clinical presentation.
• To assess DaT imaging's utility in patients exposed to neuroleptics within a specialized movement disorders center.

Main Methods:

• Retrospective chart review of 65 patients undergoing DaTscans between August 2011 and December 2012.
• Analysis of changes in clinical diagnosis and patient management following DaT scan results.

Main Results:

• DaT scan results led to a change in clinical management for 63% of patients.
• The imaging procedure enhanced diagnostic confidence among clinicians.

Conclusions:

• DaT imaging significantly influences clinical management decisions for patients with uncertain parkinsonian syndromes.
• DaT scans are a valuable tool in tertiary referral centers for movement disorders.
