科学领域:

  • 医疗成像中的人工智能
  • 机器学习用于医疗保健
  • 放射学 信息学 信息学

背景情况:

  • 目前用于医疗图像的自我监督学习往往忽略了有价值的电子健康记录 (EHR) 数据.
  • 整合多样化的患者和扫描信息可能会提高模型性能.

研究的目的:

  • 开发一个多式预训练策略,用于胸部X射线图,并结合EHR数据.
  • 为了提高胸部X射线成像的质量,使用蒙面族网络 (MSN).

主要方法:

  • 提出了一个多式联网的蒙面族网络 (MSN),将EHR数据 (人口统计,扫描元数据,住院) 与胸部X射线图集成在一起.
  • 评估了使用ViT-Tiny和ViT-Small骨干对MIMIC-CXR,CheXpert和NIH-14数据集的方法.
  • 通过线性评估和接收器操作特征曲线 (AUROC) 下的面积来评估表示质量.

主要成果:

  • 多式联网MSN显著提高了对香草MSN和最先进的基线的表示质量.
  • 与香草MSN相比,实现了2%的AUROC改进,与其他基线相比,提高了5-8%.
  • 人口特征证明了最实质性的绩效提升.
