Summary:
«The red dot algorithm, from Behold.AI, has shown positive initial results. It has more than halved the time between initial x-ray screening and a CT scan – the gold standard for detecting lung cancer.»
«The AI technology prioritises which x-rays require urgent attention from a radiologist. This has led to the time between chest x-ray and CT scan falling to 2.8 days, from seven days.»
«Dr Paul Burn, consultant radiologist at Somerset NHS Foundation Trust, said: “There’s been a lot of buzz about AI at radiology meetings, but there’s little experience of using it in an NHS trust. We embarked on a bottom-up initiative to test the algorithm, with the aim of helping us improve our referral times.”»
«A study found that of the 562 chest exams that were classified as high confidence normal by the red dot algorithm, radiologists disagreed with just 13 of the cases. This gave a negative predictive value of 97.7 per cent.»
