Kidney diseases pose a significant global health challenge, requiring precise diagnostic tools to improve patient outcomes. This study addresses this need by investigating three main categories of renal diseases: kidney stones, cysts, and tumors. Utilizing a comprehensive dataset of 12,446 CT whole abdomen and urogram images, this study developed an advanced AI-driven diagnostic system specifically tailored for kidney disease classification. The innovative approach of this study combines the strengths of traditional convolutional neural network architecture (AlexNet) with modern advancements in ConvNeXt architectures. By integrating AlexNet's robust feature extraction capabilities with ConvNeXt's advanced attention mechanisms, the paper achieved an exceptional classification accuracy of 99.85%. A key advancement in this study's methodology lies in the strategic amalgamation of features from both networks. This paper concatenated hierarchical spatial information and incorporated self-attention mechanisms to enhance classification performance. Furthermore, the study introduced a custom optimization technique inspired by the Adam optimizer, which dynamically adjusts the step size based on gradient norms. This tailored optimizer facilitated faster convergence and more effective weight updates, imporving model performance. The model of this study demonstrated outstanding performance across various metrics, with an average precision of 99.89%, recall of 99.95%, and specificity of 99.83%. These results highlight the efficacy of the hybrid architecture and optimization strategy in accurately diagnosing kidney diseases. Additionally, the methodology of this paper emphasizes interpretability and explainability, which are crucial for the clinical deployment of deep learning models.
肾脏疾病是全球健康面临的重大挑战,需要精确的诊断工具来改善患者的预后。本研究通过调查肾结石、囊肿和肿瘤这三类主要的肾脏疾病,满足了这一需求。本研究利用了一个包含 12446 例 CT 全腹部和尿路造影图像的综合数据集,为肾脏疾病分类开发了一个先进的人工智能驱动的诊断系统。本研究的创新方法结合了传统卷积神经网络架构(AlexNet)和现代 ConvNeXt 架构的优势。通过将 AlexNet 的强大特征提取能力与 ConvNeXt 的先进注意力机制相结合,该论文实现了 99.85%的卓越分类准确性。该研究方法的一个关键进展在于两个网络的特征的战略融合。本文将层次空间信息进行串联,并引入自注意力机制,以提高分类性能。此外,该研究引入了一种受 Adam 优化器启发的定制优化技术,该技术根据梯度范数动态调整步长。这种定制的优化器促进了更快的收敛和更有效的权重更新,从而提高了模型性能。该研究的模型在各种指标上都表现出色,平均精度为 99.89%,召回率为 99.95%,特异性为 99.83%。这些结果突出了混合架构和优化策略在准确诊断肾脏疾病方面的有效性。此外,本文的方法强调了可解释性,这对于深度学习模型在临床中的应用至关重要。
