Ex­perts in Ja­pan use AI to di­ag­nose stom­ach cancer

BioSpectrum (Asia) - - Science News -

Re­searchers at Riken and the Na­tional Cancer Cen­tre in Ja­pan have suc­ceeded in us­ing artificial in­tel­li­gence (AI) to iden­tify early-stage stom­ach cancer with high ac­cu­racy. Ac­cord­ing to the re­searchers, it took AI only 0.004 sec­ond to judge whether an en­do­scopic im­age showed stom­ach cancer in the early stages or nor­mal stom­ach tis­sue. AI cor­rectly de­tected cancer in 80 per cent of cancer images, while the ac­cu­racy rate was 95 per cent in cor­rectly judg­ing nor­mal tis­sue. The re­search team at the in­sti­tutes pre­pared 100 en­do­scopic images of earlystage stom­ach cancer and 100 images of nor­mal stom­ach tis­sue for test­ing how AI spots cancer, through a method known as deep learn­ing. The re­searchers aim to put AI into prac­ti­cal use as a de­vice sup­port­ing doc­tors in mak­ing di­ag­noses.
