Objective:

To evaluate the effectiveness of a machine-learning radiomics model derived from lumbar spine CT in detecting osteoporosis compared to traditional osteoporosis detection methods.

Approach:
    Key Findings:
    • The radiomics model outperformed vertebral bone quality scoring and Hounsfield unit measurements in detecting osteoporosis.
    • The XGBoost model achieved an area under the curve of 0.89 in the training cohort and 0.91 in the test cohort, demonstrating superior performance compared to traditional methods.
    • Sensitivity was approximately 89%, specificity was 82%, and negative predictive value was 94% in the test cohort.
    Interpretation:

    The radiomics-XGBoost model demonstrates superior predictive accuracy for osteoporosis detection and may serve as an effective complementary screening tool.

    Limitations:
    • Retrospective, single-center design.
    • Modest sample size.
    • Use of a single CT scanner and acquisition protocol.
    • Inability to stratify patients with osteopenia, which may limit applicability.
    Conclusion:

    The radiomics-XGBoost model shows promise as a screening tool for osteoporosis, necessitating external validation in multicenter cohorts.
