New software built in Japan can detect bowel cancer in less than a second, researchers claim.
In recently-conducted trials, the artificial intelligence (AI)-powered system was able to spot colorectal adenomas — which are benign tumours that can evolve into cancer — from magnified endoscopic images. The images were matched against 30,000 others that were used for machine learning.
The system analysed more than 300 colorectal adenomas in 250 patients, taking less than a second to assess each magnified endoscopic image and determine the malignancy of the tumours with 94 percent accuracy, researchers claim.
“The most remarkable breakthrough with this system is that AI enables real-time optical biopsy of colorectal polyps during colonoscopy, regardless of the endoscopists’ skill,” said study leader Dr Yuichi Mori from Showa University in Yokohama, Japan, who presented the results at United European Gastroenterology Week in Barcelona.
