A domain-adaptive deep contrastive network for magnetic resonance imaging-driven bladder cancer classification
This paper proposes a Domain-Adaptive Deep Contrastive Network (DADCNet) for MRI-based bladder cancer classification, addressing challenges of inter-center distributional discrepancies and limited feature discriminability. It jointly incorporates source- and target-domain samples during feature learning to achieve domain-invariant and discriminative representations, improving cross-center generalization. A deep contrastive learning strategy further enhances inter-class separability and intra-class compactness for robust classification. Experimental results on a multi-center MRI dataset show DADCNet outperforms existing CNN- and Transformer-based methods, achieving 0.955 accuracy, 0.955 F1-score, and 0.991 AUC, demonstrating superior robustness and cross-domain generalization, highlighting its clinical value.

Clinical Relevance: Interpretability of Findings
Interpretability analysis (Grad-CAM, t-SNE) confirms DADCNet's focus on clinically relevant regions, aligning with radiologists' diagnostic criteria.
Clinical Validation Through Interpretability
Client: Bladder Cancer Patients / Radiologists
Ensuring model decisions align with medical understanding and improving clinical adoption.
Utilized Grad-CAM to visualize activation maps, showing DADCNet focuses on tumor regions and muscular layers (critical for MIBC/NMIBC distinction). t-SNE plots demonstrated clear separation of NMIBC and MIBC clusters over training epochs.
Outcome: The model's interpretability confirms its clinical meaningfulness, building trust and supporting its strong potential for pre-operative diagnosis and personalized treatment planning.
