MRI Radiomics Plus Clinical Factors Predicts VETC and Early Recurrence in Small HCC

Radiology AI literature (PubMed)5d ago

Combined MRI radiomics+clinical model predicted VETC positivity in HCC ≤3cm with AUCs 0.885 (training), 0.867 (validation), 0.849 (external validation). Also stratified early recurrence risk (p<0.05).

  • Retrospective study of 336 patients with HCC ≤3 cm (training n=192, internal validation n=79, external validation n=65).
  • Combined clinical-radiomics model AUCs: 0.885 (training), 0.867 (validation), 0.849 (external validation); outperformed standalone clinical and radiomics models.
  • Limitation: retrospective design; requires prospective validation before clinical use.
