This measurement involves a subjective interpretation of vertebrae position and angle calculation, and inter-observer variability is widely accepted as one of the main causes of diagnosis uncertainty. PURPOSE: Our objective was to develop an automated and reproducible system based on artificial intelligence (AI) to assist in Cobb angle estimation on full-spine radiographs without human intervention. STUDY DESIGN: Retrospective, observational, multicenter study. METHODS: We performed a multicenter study involving four tertiary hospitals in which we collected full-spine anteroposterior/posteroanterior (AP/PA) X-ray images from AIS patients with Cobb angles ranging from mild to sever","pubDate":"2026-10-19T06:49:10Z","url":"https://doi.org/10.1016/j.spinee.2026.01.010"},"indexado":"2026-10-21T05:32:19.019Z"}}
