Excel Diagnostics

Excel Diagnostics proudly offers the first and only FDA approved DIAGNOSTIC PET TRACER for imaging Beta-Amyloid Neuritic Plaques seen in Alzheimer’s disease.

We are excited to announce the addition of Amyvid Scan to our “Excel Molecular Neurology Imaging” portfolio. For the first time in clinical practice, sales clinic physicians can utilize PET imaging to see evidence of amyloid plaques in the brain of their patients.  Amyvid (F-18 Florbetapir) is a radioactive diagnostic agent recently approved by the FDA for PET/CT imaging of the brain to estimate beta-amyloid neuritic plaque density in adult patients with cognitive impairment who are being evaluated for Alzheimer’s disease and other causes of cognitive decline.

  • Alzheimers disease is one of the many possible causes of cognitive decline.
  • Beta-amyloid is one of the necessary pathological features of Alzheimer’s disease.
  • Amyvid is the first and only FDA approved diagnostic PET tracer for imaging beta-amyloid neuritic plaques in the living brain.
  • There is a statistically significant correlation between median Amyloid PET scan scores and percentage of cortical amyloid burden at autopsy.
  • Amyvid has a 96% sensitivity and 100% specificity for Amyloid plaques in patients with autopsies performed within 1 year of Amyvid scan.


Amyvid is injected into the blood stream, thumb where it crosses the blood-brain barrier and binds to amyloid plaques. The radiolabeled  fluorine 1

8 (F-18) isotope produces a positron signal, which is detected by a PET scanner. A positive scan is highly suggestive of the Alzheimer`s disease (when considered in an appropriate clinical setting) and a negative scan rules out the diagnosis of Alzheimer`s disease. More information can be found at www.Amyvid.com. The safety and effectiveness of Amyvid have not been established for predicting the development of dementia or other neurological condition, or for monitoring response to therapies.

We also provide other Neurology Imaging modalities on our state-of-the-art equipment: Brain FDG PET/CT Scan, DaT Scan / Dopamine Transporter Scintigraphy, and MRI of the brain. Feel free to call us with any questions or if you need more information. We look forward to providing this exciting new service to your patients.
