Computer-driven artificial intelligence (AI) can help protect human brains from the damage wrought by stroke, a new report suggests. A computer program trained to look for bleeding in the brain outperformed two of four certified radiologists, finding abnormalities in brain scans quickly and efficiently, the researchers reported. “This AI can evaluate the whole head in one second,” said senior researcher Dr. Esther Yuh, an associate professor of radiology at the University of California, San Francisco. “We trained it to be very, very good at looking for the kind of tiny abnormalities that radiologists look for.” Stroke doctors often say that “time is brain,” meaning that every second’s delay in treating a stroke results in more brain cells dying and the patient becoming further incapacitated. Yuh and her colleagues hope that AI programmed to find trouble spots in a brain will be able to significantly cut down treatment time for stroke patients. “Instead of having a delay of 20 to 30 minutes for a radiologist to turn around a CT scan for interpretation, the computer can read it in a second,” Yuh said. Stroke is the fifth-leading cause of death in the United States, and is a leading cause of disability, according to the American Stroke Association. There are two types of strokes: ones caused by burst blood vessels in the brain (hemorrhagic), and others that… read on >
