- Original description
This study is a retrospective analysis that uses abdominal CT scans, which were originally taken for other medical reasons, to estimate bone age. By applying advanced deep learning methods, the investigators aim to develop a tool that can evaluate bone health and detect early signs of osteoporosis without requiring additional scans or radiation. This approach may help doctors better understand bone aging, improve screening for bone weakness, and provide patients with more personalized information about their bone health.Read full original descriptionShow less
Development and Evaluation of a Deep Learning-Based Model for Automated Osteoporosis Assessment Using CT Images
This study is a retrospective analysis that uses abdominal CT scans, which were originally taken for other medical reasons, to estimate bone age. By applying advanced deep learning methods, the investigators aim to develop a tool that can evaluate bone health and detect early signs of osteoporosis without requiring additional scans or radiation. This approach may help doctors better understand bone aging, improve screening for bone weakness, and provide patients with more personalized information about their bone health.
Inclusion: Adults aged over 18 years; Underwent routine noncontrast abdominal CT scans; CT scans fully included the proximal femur; Scans were performed for non-orthopedic clinical indications; Provided necessary demographic information (e.g., age, sex).
Exclusion: Severe hip deformity or prior fractures affecting the proximal femur; History of hip surgery or presence of internal fixation devices; CT scans with poor image quality or severe artifacts that precluded accurate analysis; Presence of bone tumors in the proximal femur; Pediatric patients or pregnant individuals (if applicable).
