What is a Trodat Brain Scan Test in Visit Clinic?
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.
