科学领域:

  • 整形外科手术 整形外科手术
  • 医学成像分析分析 医学成像分析
  • 医疗保健中的人工智能

背景情况:

  • 膝关节骨关节炎是导致残疾的主要原因,通常需要骨科干预.
  • 准确评估下肢机械对齐使用承重长腿X射线图 (LLR) 对于膝盖伤害管理至关重要.
  • 目前的LLR分析方法耗时且容易出现错误,需要改进技术.

研究的目的:

  • 开发和验证深度学习 (DL) 模型,用于对前后LLR腿部对齐的完全自动评估.
  • 提高骨科手术前规划中腿部对齐分析的可靠性和效率.
  • 在准确性,可靠性和速度方面,比较DL模型与骨科外科医生的性能.

主要方法:

  • 一项多中心研究开发了一个DL模型,使用594个LLR,使用一个检测网络和九个专门网络进行全面的对齐评估.
  • 该DL模型在不同的机构数据集上进行了培训,验证和测试.
  • 在DL模型和三个骨科外科医生之间比较了包括精度,评分器间可靠性 (ICC) 和分析持续时间在内的性能指标.

主要成果:

  • 与骨科外科医生相比,DL模型表现出相当的对齐精度 (DL:0.21 ± 0.18°至1.06 ± 1.3°与OS相比:0.21 ± 0.16°至1.72 ± 1.96°) 和间隔器可靠性 (DL ICC:0.90 ± 0.05至1.0 ± 0.0与OS ICC:0.90 ± 0.03至1.0 ± 0.0).
  • 临床上可接受的准确度为DL模型的53.9%-100%,而外科医生则为30.8%-100%.
  • 自动化分析时间显著减少 (DL: 22 ± 0.6 秒与OS: 101.7 ± 7 秒,p ≤ 0.01).

结论:

  • 开发的深度学习算法提供了一种准确可靠的方法,用于在LLR上进行自动化腿部对齐评估.
  • 人工智能模型与专家骨科外科医生的精度相匹配,同时显著提高了分析速度和一致性.
  • 这项研究强调了人工智能在骨科实践中提高临床效率和决策的潜力.
