“The Ultimate Second Opinion”: AI Just as Good as Doctors at Analysing X-rays - Technology Org | By The Digital Insider

on

AI can analyse X-rays and diagnose medical issues just as, or more, accurately than doctors, a new study led by the University of Warwick has found.

The AI, which has been trained on 2.8 million historic chest X-rays from over 1.5 million patients, scans X-Rays for 37 possible conditions.


It was just as accurate or more accurate than the doctor’s analysis at the time the X-ray was taken for 35 out of 37 conditions (94%).


The AI software can scan X-rays as soon as they are taken for possible conditions and flags any abnormalities. It will then give a percentage chance of each of the abnormalities being present. The AI also understands the seriousness of the different conditions and will flag the more urgent ones to doctors accordingly.


To verify the accuracy of the AI, a sample of over 1,400 X-Rays it had analysed were cross examined by a group of senior radiologists, who compared the diagnoses made by the AI with the historical diagnoses by radiologists at the time.


The AI is a collaboration between Warwick, King’s College London and several NHS sites funded by a Wellcome Trust Innovator Award. The programme also uses a large language model to understand the historical reports written by clinicians – the same underlying technology used by other AI programmes, such as ChatGPT.


Dr Giovanni Montana, Professor of Data Science at Warwick, and lead author, suggested that the AI tool could either be used as a screening tool for radiologists, or to offer “the ultimate second opinion”, avoiding human bias.


Dr Montana commented: “This programme has been trained on millions of X-rays and is highly accurate. It eliminates the elements of human error, which is unavoidable, and bias. If a patient is referred for an X-ray with a heart problem, doctors will inevitably focus on the heart over the lungs.


“This is totally understandable but runs the risk of undetected problems in other areas. This AI eliminates that human bias – it’s the ultimate second opinion”.


Co-author Professor Vicky Goh of King’s College London, and immediate past Chair of the Academic Committee at the Royal Society of Radiologists commented: “Current AI programmes available to us in the NHS only have a limited scope. Comprehensive AI programmes like this will be the future of medicine, with AI acting as a co-pilot for busy doctors.


“With the acute shortage of radiologists in the UK, programmes like this will facilitate interpretation and reduce delays for diagnosis and treatment”.


There is also the possibility that the AI could look at the X-Rays where no abnormalities are found, which is around half of all of them, and flag this to doctors in a way which could improve efficiency for the NHS. By allowing AI to weed out X-Rays with no abnormalities found, radiologists will have more time to focus on challenging and more critical tests.


A recent poll by the Royal College of Radiologists found that shortages of radiologists were leading to longer wait times, and delays in treatment, at 97% of the UK’s cancer treatment centres.


This AI software – entitled X-Raydar – is designed to help reduce the workload for doctors and cut delays. Remarkably, the research group has open sourced the entire software for non-commercial uses to speed up the pace of research development in this domain.


The software can be seen in use in a video here.
