AI identifies early signs of prostate cancer from CT scans

CT imaging is not suitable for regular cancer screening because of the high radiation doses involved, but RMIT believe the AI solution - developed in collaboration with clinicians at St Vincent's Hospital Melbourne - could be used to run a cancer check whenever men have their abdomen or pelvis scanned for other issues. The research is detailed in Scientific Reports.

RMIT's Dr Ruwan Tennakoon said CT scans were good for detecting bone and joint problems but radiologists struggled to spot prostate cancers on the images.

"We've trained our software to see what the human eye can't, with the aim of spotting prostate cancer through incidental detection," he said in a statement.

"It's like training a sniffer dog - we can teach the AI to see things that we can't with our own eyes, in the same way a dog can smell things human noses can't."
