Can a DaTscan diagnose Lewy body dementia?
DaTscan is unable to discriminate between Parkinson’s Disease, Multiple System Atrophy and Progressive Supranuclear Palsy. To help differentiate probable dementia with Lewy bodies from Alzheimer’s disease. DaTscan is unable to discriminate between dementia with Lewy bodies and Parkinson’s disease dementia.
What does a DaTscan reveal?
DaTscan is FDA approved to differentiate between essential tremor and Parkinsonian syndrome. Parkinson’s disease is the most common form of Parkinsonian syndrome, but there are other forms, including multiple system atrophy and progressive supranuclear palsy.

Only in the study of patients with clinically uncertain parkinsonism, a high diagnostic accuracy of DAT SPECT imaging was observed with sensitivity and specificity rates of 98%.
What is the difference between a PET scan and a DaTscan?
There are several compounds available for use in both PET and SPECT scanning; however PET scans typically focus on glucose (sugar) metabolism, and DaT/SPECT scans focus on the activity of the dopamine transporter.
Do Lewy bodies show on MRI?
HealthDay News — Magnetic resonance imaging (MRI) of the brain may aid diagnosis of dementia with Lewy bodies versus Alzheimer’s disease, according to a study published online Nov. 2 in Neurology.
Can you see Lewy bodies on an MRI?
Imaging techniques like computerized tomography (CT) scans and magnetic resonance imaging (MRI) scans have been around for many years and have been vital tools in diagnosing a very wide variety of diseases. While neither is diagnostic of Lewy body dementia (LBD), they can assist the physician in diagnosis.
How do they test for Lewy body dementia?
There are no tests that can definitively diagnose LBD. Currently, only a brain autopsy after death can confirm a suspected diagnosis. However, researchers are studying ways to diagnose LBD earlier and more accurately during life.
