·clinical-trialsA landmark 3,000-participant prospective trial from Guangdong Provincial People's Hospital will pit three CT-based AI models — MVCS, LungDoc, and United Imaging — head-to-head for pulmonary nodule malignancy prediction, using surgical pathology as the gold standard. The study addresses a critical evidence gap in AI diagnostic validation that is directly relevant to clinicians managing the growing burden of incidental and screen-detected lung nodules. Results anticipated by 2028 could reshape nodule risk stratification workflows globally.
