Advocate Lutheran General Hospital in Park Ridge, Ill., is using artificial intelligence-powered software that can recognize and respond to stroke within minutes, according to a Jan. 2 WTTW report.

The software, called Viz.AI, leverages deep learning and applies an algorithm to analyze a patient's brain scan to detect signs of a stroke. 

"That workflow, normally, is someone would go to a hospital [emergency room], wait for a radiologist, then a specialist would be called — that can take 45 minutes, sometimes beyond an hour," Demetrius Lopes, MD, who serves as director of Advocate Health Care's stroke program, told the network. "This whole process has been cut down to about six minutes."

After the software scans the patient's MRI or CT scan, the technology can immediately notify the hospital's stroke team of the results via smartphone.
