1
A machine-learning radiomics model from lumbar spine CT outperformed traditional methods in detecting osteoporosis.
2
The study analyzed 166 patients, identifying 210 vertebrae classified as osteoporotic based on dual-energy X-ray absorptiometry.
3
The XGBoost model achieved an area under the curve of 0.89 in training and 0.91 in testing, indicating high predictive performance.
4
The radiomics model demonstrated greater net clinical benefit compared to vertebral bone quality scores and Hounsfield unit measurements.
5
Limitations of the study included its retrospective design, modest sample size, and the need for external validation in multicenter cohorts.
