An artificial intelligence tool that can detect tiny, hard-to-spot brain malformations in children with epilepsy could help patients access life-changing surgery quicker, Australian researchers said on Wednesday. Epilepsy has several different causes, and overall around three in 10 cases are down to structural abnormalities in the brain, experts say. A team led by Emma Macdonald-Laurs, a paediatric neurologist at the Royal Children's Hospital in Melbourne, trained an AI tool on child brain images to find lesions the size of a blueberry or smaller.

Similar research published in February by a KCL team using AI on MRI data spotted 64 percent of epilepsy-linked brain lesions that were missed by radiologists.
