Frequently asked questions about MRI, FDG-PET

What is MRI, FDG-PET used for in Alzheimer's Disease?

MRI, FDG-PET is an investigational imaging approach being studied for use in Alzheimer's Disease. It was evaluated in a Phase 1 clinical trial as a potential biomarker to assess regional cerebral blood flow compared to positron emission tomography in patients with mild-to-moderate Alzheimer's Disease and cognitively normal elderly subjects.

Who makes MRI, FDG-PET?

MRI, FDG-PET is being developed by Merck & Company, Inc., which trades under the ticker MRK. The company sponsored a Phase 1 clinical trial of this imaging approach in Alzheimer's Disease.

What phase is MRI, FDG-PET in?

MRI, FDG-PET is in Phase 1 clinical development. It has completed one Phase 1 trial in Alzheimer's Disease, and it remains an investigational imaging approach that is not approved for clinical use.

What clinical trials is MRI, FDG-PET in?

MRI, FDG-PET has been studied in one completed Phase 1 clinical trial, NCT00757939. This trial assessed regional cerebral blood flow as an Alzheimer's Disease biomarker compared to positron emission tomography in patients with mild-to-moderate Alzheimer's Disease and cognitively normal elderly subjects, enrolling 40 participants.

Is MRI, FDG-PET FDA approved?

MRI, FDG-PET is not FDA approved. It is an investigational imaging approach that has completed a Phase 1 clinical trial in Alzheimer's Disease, but it remains in clinical development and has not been approved for any use.
