StateViewer
Overview
StateViewer is an artificial intelligence (AI) tool developed by Mayo Clinic’s Neurology Artificial Intelligence Program (NAIP) designed to assist clinicians in diagnosing various neurodegenerative diseases, particularly dementias.
What it does: StateViewer analyzes fluorodeoxyglucose positron emission tomography (FDG-PET) brain scans. It compares an individual patient’s scan to a large database of confirmed dementia cases to identify patterns of brain activity and glucose metabolism associated with specific types of dementia. The tool can identify patterns linked to nine types of dementia, including Alzheimer’s disease, Lewy body dementia, and frontotemporal dementia.
Who it is for: This tool is intended for neurologists and other clinicians involved in the diagnosis and management of patients with suspected neurodegenerative conditions. It may be particularly beneficial in care settings that may lack immediate access to specialized neurology expertise.
How it fits a clinical or practice workflow: StateViewer integrates into the diagnostic workflow by providing an AI-powered analysis of FDG-PET scans. The tool generates color-coded brain maps that visually highlight key areas of brain activity, offering a visual explanation of the AI’s findings to clinicians. This output can be reviewed during multidisciplinary case conferences to support diagnostic decision-making.
Notable capabilities: StateViewer has demonstrated the ability to identify dementia types with an 88% accuracy rate in studies. It has also been shown to potentially enhance the speed of scan interpretation and diagnostic accuracy for clinicians. The tool’s design aims to provide clear, interpretable insights to support clinicians in distinguishing between various complex neurodegenerative diseases.

- Identifies patterns linked to 9 types of dementia (e.g., Alzheimer's, Lewy body, frontotemporal dementia, posterior cortical atrophy, corticobasal syndrome, progressive supranuclear palsy)
- Compares patient scans to a large reference dataset of confirmed dementia cases (over 3,600 scans)
- Produces color-coded brain activity maps highlighting disease patterns
- Enhances diagnostic accuracy (88% accuracy in identifying dementia types)
- Increases speed of interpretation (nearly twice as fast as standard workflows)
- Improves diagnostic accuracy for clinicians (up to three times greater accuracy than standard practices)
- Aids in distinguishing between dementias with similar symptoms
- Provides visual explanations of AI findings for clinicians
- Designed to support, not replace, clinical decision-making
Use Cases
- Early and precise diagnosis of various dementia types
- Supporting clinical decision-making in neurology
- Expanding access to specialist-level insights in clinics lacking neurology expertise
- Guiding treatment decisions for patients with dementia
- Differentiating between multiple overlapping or coexisting dementia conditions

What Physicians Need to Know
StateViewer is a powerful AI tool designed to augment, not replace, clinical decision-making in diagnosing dementia. Leverage its ability to rapidly analyze FDG-PET scans and provide color-coded brain maps to enhance diagnostic accuracy and differentiate between complex neurodegenerative phenotypes, especially in cases with overlapping symptoms. The tool can significantly reduce interpretation time and offer expert-level insights, potentially expanding access to specialized dementia diagnostics.
StateViewer is a Mayo-created platform that takes an individual patient's PET scan and applies AI to find similar cases of brain disease in Mayo's distributed data network. It operates within the Mayo Clinic Cloud, an innovative technology platform developed in collaboration with Google Cloud, allowing real-time access and analysis of clinical imaging data. The platform, called NetD, connects cloud-based data, multimodal models, and clinical workflows to enable scalable and adaptive neurology. StateViewer is considered a Class 2 software as a medical device for analytics.

What the Web Says
StateViewer is an AI tool developed by Mayo Clinic researchers to identify nine types of dementia, including Alzheimer's disease, from a single FDG-PET brain scan. It has shown high accuracy (88%) in identifying dementia types and can help clinicians interpret brain scans nearly twice as fast and with up to three times greater accuracy than standard methods. The tool provides color-coded brain maps to visually explain the AI's findings, making it accessible even to clinicians without specialized neurology training.
Overall: PositiveStrengths
- High accuracy in identifying nine types of dementia (88%).
- Significantly faster interpretation of brain scans (nearly twice as fast).
- Up to three times greater diagnostic accuracy compared to standard workflows.
- Aids in early and precise diagnosis, even with multiple co-occurring conditions.
- Provides visual, color-coded brain maps for easier interpretation by all clinicians.
- Potential to expand advanced diagnostic support to clinics lacking neurology expertise.
Limitations
- Currently a research tool, with plans for expanded use and evaluation in various clinical settings.
- The discovery cohort for training and testing may not fully represent broader clinical populations.
- No information available from independent tech reviewers, Reddit, G2, or Capterra, indicating limited public or widespread commercial use/review outside of Mayo Clinic's research.
