Image analysis of diabetes pathology: classifying with precision via an upgraded resnet50 framework

Year: 2025

Type: article

Abstract: ABSTRACT Diabetes is a growing global health issue, and effective diagnostic tools are needed to support early detection. This study proposes an enhanced deep learning framework, SE-ResNet50, which integrates a squeeze-and-excitation (SE) block into the conventional ResNet50 architecture to improve the classification of diabetic kidney pathology from glomerular images. The SE block adaptively recalibrates feature responses, enabling the model to emphasize diagnostically relevant structures better. The proposed framework was trained and validated on a kidney tissue dataset from Kanazawa Medical University, achieving superior performance with an accuracy of 97.02%, precision of 0.96, and an AUC of 0.9856. SE-ResNet50 exhibited superior robustness and generalizability compared to established CNN architectures such as EfficientNet B0, Inception V3, and ConvNeXt. Further visualization via Grad-CAM revealed that the model effectively localizes critical regions within glomerular images. These results highlight the potential of SE-ResNet50 as a reliable and interpretable tool for advancing diabetes-related CKD diagnosis in clinical settings.
