Editor's Note

A new study from researchers in Hong Kong finds that the MAIL2.0 nowcast artificial intelligence (AI) algorithm, which was developed with concepts used in economics and meteorology, yields a high level of accuracy for identifying COVID-19 in chest x-rays, the May 5 reports.

The algorithm yielded 84.7% sensitivity, 71.6% specificity, and 0.81 area under the curve (AUC) in identifying COVID-19 in chest x-rays, compared with 31.9% sensitivity, 62.5% specificity, and 0.47 AUC with consensus radiologist interpretations.

The AI model significantly outperformed radiologists, the researchers say.
