The study compares 2D, 2.5D, and 3D residual networks for classifying pulmonary nodule malignancy risk using a retrospective LIDC‑IDRI cohort of 2,654 nodules. Models were trained with random initialization, momentum‑contrast pretraining, and mild data augmentation, and evaluated on patient‑disjoint splits. Augmented 2.5D models achieved the highest test Macro‑F1 (0.6537) and accuracy (0.6869), while 2D and 3D models performed lower, and pretraining generally reduced performance.
Purpose: To compare 2D, 2.5D, and 3D residual networks for pulmonary nodule malignancy-risk classification and evaluate momentum-contrast pretraining, mild augmentation, and exclusion of indeterminate...

FedHisto-PAST v2 is a parameter‑efficient, stain‑aware federated learning framework for cross‑site lung histopathology classification, combining a frozen HIBOU‑B foundation model with techniques such as paired‑view prediction, feature consistency, prototype learning, and adaptive aggregation. In a five‑client, non‑IID simulation and an exploratory LungHist700 cohort, the method achieved a Macro‑F1 of 0.7286 and a balanced accuracy of 0.7305, with the prediction‑level consistency component providing the most clear independent benefit. The framework updated only about 1.25% of the model parameters, demonstrating efficient adaptation while acknowledging limitations in privacy guarantees and clinical validation.
