A brain SPECT scan that measures dopamine transporter activity to help diagnose Parkinsonian disorders and guide care.
A Trodat Brain Scan measures how much dopamine transporter activity is present in the brain's basal ganglia. Dopamine transporters help regulate signals that control movement. Reduced uptake often means loss of dopamine nerve terminals. This is important for diagnosing Parkinsonian disorders and some types of dementia. Doctors use the scan to distinguish Parkinson disease from essential tremor or drug-induced movement problems. It can guide treatment decisions and show whether degeneration of dopamine pathways is likely. The test involves injecting a small radioactive tracer and taking images with a SPECT camera.
Avoid certain Parkinson's and antidepressant medications for 48–72 hours; inform if pregnant or breastfeeding.
The Trodat Brain Scan test evaluates various parameters related to the different components. Here are the main parameters that are checked in the test:
Trodat Brain Scan is a nuclear medicine dopamine transporter imaging test often ordered when patients have unexplained tremor, slowness, stiffness, or balance problems. It helps distinguish Parkinson disease from essential tremor, drug-induced parkinsonism, or atypical Parkinson syndromes and can aid dementia evaluation. Abnormal results usually reflect neurodegeneration but can be affected by certain medications or brain injury. A family history of Parkinsonism may make this scan more relevant.
