AI-Assisted Neuroimaging for ARIA Detection

Dr Benzinger:

Several artificial intelligence (AI)–assisted tools are now available to support ARIA detection and monitoring. In the US, products from Icometrix and Cortechs have received FDA clearance.14,15

Potential Utility of AI-Assisted Neuroimaging

Dr Benzinger:

These tools can assist radiologists with identifying subtle imaging features. Typically, at least 2 MRI time points are required, and automated comparison is used to identify interval changes suggestive of ARIA, such as new areas of FLAIR hyperintensity or new microhemorrhages. Many groups are using these tools and find them helpful for detecting subtle findings. The caveat is that they might also introduce additional false positives or quality control questions that require follow-up.16-18 These tools certainly cannot replace radiologists, but can definitely be included in workflows for many radiology groups. Although AI tools can help with standardization and inter-reader variability, independent review and final interpretation by a radiologist is essential.
