摘要:

肝脏纤维化代表了全球重大健康负担,需要准确的分期以实现有效的临床管理。本报告介绍了LiQA(肝脏纤维化量化与分析)数据集,该数据集是CARE 2024挑战的一部分。该数据集包含440名患者多期、多中心MRI扫描,旨在评估在复杂现实条件下,如领域转移、缺失模态和空间错位等情况下,算法在肝脏分割(LiSeg)和肝脏纤维化分期(LiFS)中的性能。我们进一步描述了挑战中表现最佳的方法,该方法结合了半监督学习框架与外部数据进行稳健分割,并利用多视图共识方法与基于类激活图(CAM)的正则化进行分期。对这一基线方法的评估显示,利用多源数据和解剖学约束显著增强了临床环境中的模型鲁棒性。

英文摘要:

Liver fibrosis represents a significant global health burden, necessitating accurate staging for effective clinical management. This report introduces the LiQA (Liver Fibrosis Quantification and Analysis) dataset, established as part of the CARE 2024 challenge. Comprising $440$ patients with multi-phase, multi-center MRI scans, the dataset is curated to benchmark algorithms for Liver Segmentation (LiSeg) and Liver Fibrosis Staging (LiFS) under complex real-world conditions, including domain shifts, missing modalities, and spatial misalignment. We further describe the challenge's top-performing methodology, which integrates a semi-supervised learning framework with external data for robust segmentation, and utilizes a multi-view consensus approach with Class Activation Map (CAM)-based regularization for staging. Evaluation of this baseline demonstrates that leveraging multi-source data and anatomical constraints significantly enhances model robustness in clinical settings.
