摘要:
本研究引入了一个自动化深度学习框架,用于从T2加权MRI(dHCP数据集)预测早产儿脑损伤(BI)。我们提出了GloResNet,一种基于ResNet-10的轻量级3D CNN,并在MedicalNet上预训练以应对数据稀缺。一种全局流形映射策略首先将每个3D体积重采样为128x128x128,然后应用逐样本z分数强度归一化,从而在标准化外观的同时保留全局拓扑。训练集成了mixup、类别加权和测试时增强以提高鲁棒性。在5折交叉验证中,GloResNet达到了75.18%的平均准确率(峰值81.82%),特异性0.81,敏感性0.76。结果表明,拓扑感知的轻量级CNN能够有效预测新生儿脑损伤,提供了一种非侵入性筛查工具。本文源代码可从GitHub仓库获取:https://github.com/ICL-SUST/GloResNet-Preterm-Brain
英文摘要:
This study introduces an automated deep learning framework for predicting brain injury (BI) in preterm infants from T2-weighted MRI (dHCP dataset). We propose GloResNet, a lightweight 3D CNN based on ResNet-10, pretrained on MedicalNet to address data scarcity. A global manifold mapping strategy first resamples each 3D volume to 128x128x128 and then applies subject-wise z-score intensity normalization, thereby preserving global topology while standardizing appearance. Training integrates mixup, class weighting, and test-time augmentation for robustness. In 5-fold cross-validation, GloResNet achieved 75.18% average accuracy (peak 81.82%), with specificity 0.81 and sensitivity 0.76. Results demonstrate that a topology-aware lightweight CNN has the capability to effectively predict neonatal BI, offering a non-invasive screening tool.
