'One wrong word in a novel': How AI can spot brain abnormalities in epilepsy patients

CGTN Europe

Imagine searching a novel for one word in a slightly different font. That's what brain scans can be like – and why AI could be a game-changer.  Read more ⬇️ https://tinyurl.com/amjvavnz   #science #medicine

00:00So about 1 in 100 people suffer from epilepsy and in about a third of these the anti-seizure

00:06medications don't help to control the seizure. For some of those patients a brain abnormality

00:11is causing these seizures. So we've made an AI tool to help diagnose hidden brain abnormalities

00:17in children and adults with epilepsy and the crucial thing is if you can find the brain

00:23abnormality you can offer surgery which might cure the seizures and what our AI tool can do

00:28is find two-thirds of those abnormalities that doctors might miss. The multi-center epilepsy

00:34lesion detection project takes data from 23 hospitals worldwide which have found 700 examples

00:39of brain abnormalities more than most radiologists would see in their lifetime.

00:44These are fed into an AI algorithm which learns what to look out for. I think it's important to

00:50kind of put into context how difficult these can be to find. So an MRI scan is maybe 10 million

00:56pixels and they're looking for something that's maybe 100 pixels at its smallest. So for context

01:02if you took a 200 page novel there's 100,000 words in it and they're looking for one word

01:07that's slightly the wrong size or slightly the wrong font and you could see how having an AI

01:11to point out potential areas can really speed up that process and also pick up things they

01:16might have missed.
