Introduction: Early detection of malignant transformation in oral potentially malignant disorders (OPMDs) is vital for improving survival in oral squamous cell carcinoma (OSCC). Conventional diagnostics, including histopathology, are invasive and subject to variability. Radiomics, which extracts quantitative features from imaging data, combined with machine learning (ML) and deep learning (DL), offers reproducible, non-invasive biomarkers to complement clinical assessment.
Discussion: Radiomics workflows involve image acquisition, segmentation, feature extraction, and predictive modeling. Applied across modalities such as CT, MRI, PET, ultrasound, autofluorescence, and optical coherence tomography (OCT), radiomic features integrated with ML algorithms enable risk stratification, guided biopsies, and longitudinal monitoring of OPMDs. Emerging technologies, including hyperspectral imaging, Raman spectroscopy, digital pathology, and liquid biopsy integration, further enhance diagnostic potential. Recent advances in software and AI platforms—such as PyRadiomics, 3D Slicer, CaPTk, MONAI, AutoRadiomics, cloud AI, federated learning, and explainability frameworks—are accelerating clinical translation. However, challenges persist due to heterogeneous data, small sample sizes, and segmentation variability. Solutions include harmonization techniques, data augmentation, robust automatic segmentation, and adherence to reporting standards.
Conclusion: Radiomics and AI-driven methods show strong promise for early, non-invasive detection of OPMD progression to OSCC. While standardization, reproducibility, and clinical validation remain barriers, advances in AI ecosystems and collaborative, multi-institutional research are paving the way toward precision diagnostics and clinical implementation.
