AI may be a reliable tool for skin cancer diagnosis – study
[ad_1]
A study has shown that the diagnosis of skin cancer with the help of artificial intelligence (AI) is as accurate as the diagnosis of doctors.
This is reported by Medical Xpress with reference to a study published in the scientific journal The Lancet Digital Health.
An Austrian-Australian research team led by dermatologist Harald Kittler compared the accuracy of diagnosis and treatment recommendations between AI and doctors.
Scientists tested two algorithms in clinical conditions – at the Department of Dermatology of MedUni University in Vienna and at the Sydney Melanoma Diagnostic Center in Australia.

The study had two scenarios. In scenario A, skin changes with suspicion of cancer were analyzed, and in scenarios B, skin with a large number of moles was analyzed.
The results of both cases were compared with the conclusions of doctors – both experts in the field and less experienced ones.
In scenario A, 172 pigmented lesions in 124 patients were examined, 84 of which were malignant.
In scenario B – 5,696 formations in 66 patients, among which 18 were malignant.
The scientists involved two AI-based applications: a new 7-class AI algorithm and the ISIC algorithm, which has already been used in research.
The new algorithm proved to be as accurate as the experts and significantly outperformed the results of inexperienced doctors.
The old algorithm showed worse results than experts, but better than less experienced doctors.
At the same time, AI coped worse with prescribing treatment. In this case, the 7-class algorithm lost to the experts, but performed better than novice doctors.
“An AI app tends to recommend removing benign lesions more often than experts would. With that in mind, an AI app is certainly usable.
It should also be borne in mind that if it is not criticized, too many false positive results will have to be clarified.” says Harold Kittler.
We will remind you that we previously wrote that scientists taught AI to diagnose brain tumors on the operating table.
