New Technology Promises to Speed Critical Treatment for Strokes

The technology from Viz.ai (the ai is for artificial intelligence) recently gained Food and Drug Administration approval. The company and Erlanger are talking to other Chattanooga hospitals about installing its diagnostic software there, which would allow neurologists to see brain scans almost simultaneously.

A Viz.ai study of 300 patients, which prompted the FDA approval, showed that the company’s software was able to notify a stroke neurologist on average 7.3 minutes after the brain imaging took place—compared with the hours that it sometimes takes with conventional diagnostic procedures. The technology accurately identified severe strokes as precisely as expert stroke radiologists do, the study found.

The system holds promise for improved outcomes, medical experts say, but only if it can be widely adopted by hospitals. One concern is cost. Companies developing the technology haven’t set a price but say it won’t be cost-prohibitive.
