    A multiparametric MRI-derived radiomics nomogram was developed to differentiate between benign, malignant, and metastatic lumbar spinal tumors.

  • 2

    The study included 100 patients with pathologically confirmed lumbar tumors, utilizing T1, T2, and fat-suppressed T2 MRI sequences.

  • 3

    The nomogram integrated 11 stable radiomics features and five independent clinical predictors, demonstrating a macro-average AUC of 0.887.

  • 4

    The model exhibited good calibration and provided superior net benefits in decision-making across various threshold probabilities.

  • 5

    This non-invasive tool has significant potential to enhance clinical decision-making for patients with lumbar spinal tumors.
