## Description

Five validated nodule malignancy models — Mayo, Brock, Herder, BIMC, and Fleischner — computed simultaneously. Fully offline.

 NoduleRisk is a clinical decision support tool for physicians evaluating
  pulmonary nodule malignancy risk. It computes probability estimates and                                               
  management guidance across five validated models simultaneously.

  NoduleRisk is intended for use by qualified clinicians as a decision support               
  aid only. Results must be interpreted in the context of the full clinical                  
  picture and do not substitute for institutional guidelines, multidisciplinary                                         
  team discussion, or clinical judgment.
