AI tool helps half of stroke patients to recoverAn AI-assisted brain scanning tool has been shown to rapidly speed up stroke diagnosis, enabling more than half of patients to recover. That’s according to England’s National Health Service, which is rolling out the tool nationwide having used it to interpret more than 60,000 brain scans already. Where deployed, it has enabled doctors to make faster decisions about treatment, the NHS said. Speedy diagnosis and treatment is critical: it’s estimated that someone who has had a stroke loses around 2m brain cells per minute. David Hargroves, NHS England’s national clinical director for stroke, said that the “technology is revolutionising how we help people who have been affected”.
