Hepatocellular carcinoma (HCC), the most common type of liver cancer, poses significant challenges in detection and diagnosis. Medical imaging, especially computed tomography (CT), is pivotal in non-invasively identifying this disease, requiring substantial expertise for interpretation. This research introduces an innovative strategy that integrates two-dimensional (2D) and three-dimensional (3D) deep learning models within a federated learning (FL) framework for precise segmentation of liver and tumor regions in medical images. The study utilized 131 CT scans from the Liver Tumor Segmentation (LiTS) challenge and demonstrated the superior efficiency and accuracy of the proposed Hybrid-ResUNet model with a Dice score of 0.9433 and an AUC of 0.9965 compared to ResNet and EfficientNet models. This FL approach is beneficial for conducting large-scale clinical trials while safeguarding patient privacy across healthcare settings. It facilitates active engagement in problem-solving, data collection, model development, and refinement. The study also addresses data imbalances in the FL context, showing resilience and highlighting local models' robust performance. Future research will concentrate on refining federated learning algorithms and their incorporation into the continuous implementation and deployment (CI/CD) processes in AI system operations, emphasizing the dynamic involvement of clients. We recommend a collaborative human-AI endeavor to enhance feature extraction and knowledge transfer. These improvements are intended to boost equitable and efficient data collaboration across various sectors in practical scenarios, offering a crucial guide for forthcoming research in medical AI.
肝细胞癌(HCC)是最常见的肝癌类型,在检测和诊断方面存在重大挑战。医学成像,特别是计算机断层扫描(CT),在非侵入性地识别这种疾病方面至关重要,需要有大量的专业知识进行解释。本研究引入了一种创新策略,即在联邦学习(FL)框架内集成二维(2D)和三维(3D)深度学习模型,用于对医学图像中的肝脏和肿瘤区域进行精确分割。该研究利用来自 Liver Tumor Segmentation(LiTS)挑战赛的 131 个 CT 扫描,展示了所提出的 Hybrid-ResUNet 模型的优越效率和准确性,其 Dice 得分为 0.9433,AUC 为 0.9965,与 ResNet 和 EfficientNet 模型相比。这种 FL 方法有利于在保护医疗保健环境中患者隐私的同时,开展大规模临床试验。它促进了在解决问题、数据收集、模型开发和改进方面的积极参与。该研究还解决了 FL 环境中的数据不平衡问题,显示出其弹性,并突出了局部模型的强大性能。未来的研究将集中于改进联邦学习算法,并将其纳入 AI 系统操作的持续实施和部署(CI/CD)过程,强调客户端的动态参与。我们建议进行人机协作,以增强特征提取和知识转移。这些改进旨在促进在实际场景中各个领域的公平和高效的数据协作,为医学 AI 中的未来研究提供重要指导。
