MedicalPatchNet: A patch-based self-explainable AI architecture for chest X-ray classification
Deep neural networks excel in radiological image classification but frequently suffer from poor interpretability, limiting clinical acceptance. We present MedicalPatchNet, an inherently self-explainable architecture for chest X-ray classification that transparently attributes decisions to distinct image regions. MedicalPatchNet splits images into non-overlapping patches, independently classifies each patch, and aggregates predictions, enabling intuitive visualization of each patch's diagnostic contribution without post-hoc techniques. Trained on the CheXpert dataset (223,414 images), MedicalPatchNet matches the classification performance (AUROC 0.907 vs. 0.908) of EfficientNetV2-S, while improving interpretability: MedicalPatchNet demonstrates improved interpretability with higher pathology localization accuracy (mean hit-rate 0.485 vs. 0.376 with Grad-CAM) on the CheXlocalize dataset. By providing explicit, reliable explanations accessible even to non-AI experts, MedicalPatchNet mitigates risks associated with shortcut learning, thus improving clinical trust. Our model is publicly available with reproducible training and inference scripts and contributes to safer, explainable AI-assisted diagnostics across medical imaging domains.

Impact in Chest X-Ray Diagnostics
In a scenario involving chest X-ray classification for various pathologies, MedicalPatchNet's inherent explainability proved crucial. Radiologists were able to visually confirm the specific image regions driving the AI's decisions for conditions like pleural effusion or atelectasis, leading to a significant increase in diagnostic confidence. This direct attribution helped in identifying and mitigating potential shortcut learning, where traditional models might rely on extraneous features. The ability to present clear, patch-level evidence allowed for faster validation of AI insights, ultimately streamlining the diagnostic workflow and improving patient care safety. Physicians reported that the 'votes' from individual patches aligned with their clinical understanding, fostering greater adoption.
