Artificial intelligence detects prostate cancer more often than radiologists - study

Artificial intelligence (AI) detects prostate cancer more often than radiologists. This is according to an international study conducted by Radbaud University Medical Center, the results of which are published in The Lancet Oncology.

This is the first large-scale study in which an international team transparently evaluates and compares AI with radiologists' assessments and clinical outcomes.

AI expert Henkjan Huisman and radiologist Maarten de Rooy organized a major competition between AI teams and radiologists with an international team. Together with other centers in the Netherlands and Norway, they performed more than 10,000 MRI scans. They determined in every patient the presence of prostate cancer.

This allowed various groups around the world to develop artificial intelligence to analyze these images. The top five materials were combined into a super algorithm to analyze the MRI scans for prostate cancer. Finally, the results of the AI evaluation were compared to the results of a group of radiologists who took four hundred MRI images of the prostate gland.

They compared the AI and radiologists' results not only to each other, but also to the gold standard as they tracked the results in the men who had the scans.

On average, the men were followed for five years. This first international study on the use of AI in prostate diagnosis shows that AI detects almost 7% more prostate cancer than a group of radiologists.

In addition, AI detects suspicious areas that later turn out to be non-cancerous 50% less often. This means that with AI, the number of biopsies could be cut in half.
