Case Study: Chest X-rays

Case Study: Chest X-rays

Learn about a practical example of model bias in the real world.

In this case study, we’ll be diving into a particular case of model bias in the medical sector. In December 2021, a paperSeyyed-Kalantari, L., et al. “Underdiagnosis Bias of Artificial Intelligence Algorithms Applied to Chest Radiographs in Under-served Patient Populations.” 2021. Pacific Symposium on Biocomputing, vol. 26, pp. 232-243. PMID: 33691020. published in Nature revealed that algorithms meant to diagnose patients based on their chest radiographs were often biased in a way that underdiagnosed underserved populations.

Background

Chest x-rays are one particularly useful area for ML and AI models to speed up diagnoses. Chest x-rays are easily obtainable data sources that have clear targets (diagnosis or no diagnosis) for medical practitioners to provide labels to. Models trained on this data become “experts” at identifying abnormalities in these images.

In the United States, patients from minority ...
