    A machine learning radiomics model integrating PET/CT and MRI shows promise for prostate cancer risk stratification.

  • 2

    The study evaluated 488 patients, with significant findings from both internal and external validation cohorts.

  • 3

    Multimodal models outperformed single-modality approaches, achieving high AUC scores for clinically significant prostate cancer.

  • 4

    Limitations include retrospective design, small validation cohorts, and lack of prospective validation affecting generalizability.

  • 5

    The findings suggest further study of multimodal radiomics as a decision-support tool, not a replacement for biopsy.
