Benson Radiology’s PET imaging team can now provide Amyloid Brain Scans on patients with cognitive impairment, being evaluated for Alzheimer’s Disease.
These scans identify the presence of beta-amyloid plaque in the brain. Beta-amyloid plaques are significant, as they are found in all patients with AD. This plaque can be present many years before clinical symptoms manifest.
A positive beta-amyloid PET scan, in conjunction with appropriate clinical evaluation, can aid an early diagnosis of AD. A negative scan can be useful in excluding AD.
As you can see from the images, no significant beta-amyloid deposition is seen in Patient 1 (top 2 rows), while Patient 2 (bottom 2 rows) shows an abnormal scan presenting with significant beta-amyloid plaque burden.
