Lung Cancer Detection AI Accurately Identifies Pre-Cancerous Growths

May 5, 2023

An artificial intelligence (AI) model developed by UK researchers identified abnormal lung growths that would later become cancerous with a high degree of accuracy. The AI model was developed in the LIBRA study using lung imaging data from 500 patients with large abonormal lung nodules. 82% of the tumors the AI model identified as high-risk were later found to be cancerous.

According to Emily Kimber, “To assess how effective the new model was at predicting cancer, the team used a measure called the area under the curve (AUC). An AUC of one would indicate a perfect model, while 0.5 would be expected if the model was randomly guessing. The results, which have been published in the Lancet’s eBioMedicine, indicate that the model was able to identify each lung nodule’s risk of cancer with an AUC of 0.87.”
