September 29 Colloquium: "Hip and Knee Bony Anatomy Segmentation in Plain Radiographs: Lessons Learned from Building Fully-annotated Imaging Datasets to Unbiased Segmentation"

Talk Abstract

AI-powered segmentation of hip and knee bony anatomy has become indispensable in orthopedics, revolutionizing both pre-operative planning and post-operative assessment. Despite the remarkable performance made by deep learning computer vision algorithms in medical image segmentation, a critical concern remains largely unexplored, and that is how to uncover and address potential biases inherent within these AI-powered models. The present contribution undertakes a comprehensive re-examination of deep learning-driven hip and knee bony anatomy segmentation employing plain radiographs, with a specific focus on revealing discernible gender and racial biases. Through an extensive evaluation, this work offers insights into underlying causes of biases, presenting targeted mitigation strategies tailored to alleviate gender and racial biases, thereby engendering automatic segmentation results that are fair, impartial, and safe in the context of AI. As AI-powered medical imaging continues to advance, the lessons gleaned from this study will furnish invaluable intuitions guiding the development of deep learning models toward a more inclusive, ethically sound, equitable, and unbiased healthcare landscape.
