Description
A DaTscan, also known as a Dopamine Transporter (DaT) Scan, is a specialized nuclear medicine imaging test used to visualize dopamine transporter levels in the brain. It plays an important role in the evaluation of Parkinson’s disease and other parkinsonian syndromes by helping doctors assess the function of dopamine-producing nerve cells.
This scan uses a small amount of radioactive tracer that binds to dopamine transporters in the brain, allowing precise imaging of areas involved in movement control.
What Is a DaTscan?
A DaTscan is a type of SPECT (Single Photon Emission Computed Tomography) imaging that provides detailed information about the dopaminergic system in the brain. It helps differentiate Parkinson’s disease from other conditions that cause similar symptoms, such as essential tremor.
Why Is a DaTscan Performed?
A DaTscan is recommended to:
- Support the diagnosis of Parkinson’s disease
- Differentiate Parkinson’s disease from essential tremor
- Evaluate other parkinsonian syndromes
- Assess dopamine transporter function in the brain
How Is a DaTscan Performed?
A small amount of radioactive tracer is injected into a vein. After allowing time for the tracer to bind to dopamine transporters in the brain, the patient lies on the scanner while images are taken.
The imaging process is painless and typically takes 30 to 45 minutes.
Advantages of DaTscan
- Provides objective evidence of dopamine transporter loss
- Improves diagnostic confidence in movement disorders
- Non-invasive and safe
- Helps guide treatment decisions
Book DaTscan
If you or a loved one is experiencing symptoms such as tremors, stiffness, or movement difficulties, a DaTscan can help provide clarity and support accurate diagnosis for appropriate treatment planning.
