科学领域:

  • 数字病理学数字病理学
  • 计算病理学计算病理学
  • 医学中的人工智能

背景情况:

  • 从千兆像素整片图像 (WSIs) 准确诊断疾病至关重要,但具有挑战性.
  • 现有的计算病理学方法与WSI补丁依赖性的整体分析作斗争.

研究的目的:

  • 通过变压器 (WIT) 引入WSI检查,这是一种用于幻灯片级分类的新型上下文意识方法.
  • 提高用于疾病诊断的计算病理学的准确性和可解释性.

主要方法:

  • 开发了WIT,这是一个基于变压器的模型,用于汇总WSI表示的补丁特征.
  • 采用了上下文意识的策略来建模 WSIs 内的补丁之间的依赖关系.
  • 对多个癌症数据集的最先进的基线方法评估WIT的表现.

主要成果:

  • 在TCGA上检测32种癌症类型 (82.1%) 和在CPTAC上诊断癌症 (0.918) 中,WIT取得了高准确度.
  • 从注射针活检幻灯片中在前列腺癌诊断 (0.882) 中表现出卓越的表现,表现明显优于基线.
  • WIT成功地确定了有影响力的WSI地区,为分类决策做出了贡献.

结论:

  • WIT代表了计算病理学的新范式,提供了更高的准确性和可解释性.
  • 这种方法有助于开发用于疾病诊断的先进数字病理学工具.
  • 在WIT中对上下文敏感的补丁聚合显著提高了幻灯片级分类性能.
