AI (Artificial intelligence) can be helpful in many cases. A recent study by researchers shows that it can help identify cancerous diseases.

An artificial intelligence model has been created by scientists, doctors, and researchers that can identify cancer accurately. Researchers claim it can speed up the diagnosis of the disease (the process of identifying the diseases and affected areas) and also track treatment given to the patients.

The AI tool, which ‘‘performs more efficiently and effectively than current methods’’ has been designed by experts at the Royal Marsden NHS foundation trust, the Institute of Cancer Research, London, and Imperial College London.

The Royal Marsden is a hospital in Sutton, UK operated by NHS Foundation Trust.

The tool can identify if abnormal growths seen on a person’s CT scans are cancerous or not.

The research’s findings were published in the biomedicine journal of the Lancet.

'’In the future, we hope it will improve early detection and potentially make cancer treatment more successful by highlighting high-risk patients and fast-tracking them to earlier intervention,” said Dr. Benjamin Hunter, a clinical research fellow at Imperial and a clinical oncology registrar who works at the Royal Marsden.

The team used CT scans of about 500 patients with large lung nodules to develop an AI algorithm using radiomics The technique can be used to get important information from medical images which are not easily spotted by the human eye.

The study used a measure called area under the curve (AUC) to see how effective the model was at anticipating cancer. If a model gets an AUC of 1, it indicates a perfect model, while 0.5 would be expected if the model was randomly guessing.

The results showed the AI model could spot each nodule’s risk of cancer with an AUC of 0.87. The performance improved on the Brock score, a test used in the clinic, which scored 0.67.

'’According to these initial results, our model appears to identify cancerous large lung nodules accurately. Next, we plan to test the technology on patients with large lung nodules in the clinic to see if it can accurately predict their risk of lung cancer,’’ Mr. Hunter added.

Libra study’s chief investigator, Dr Richard Lee said, ‘‘Through this work, we hope to push boundaries to speed up the detection of the disease using innovative technologies such as AI.’’
