Classification of Bones

7.3K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

科学领域:

  • 放射学 放射学是一门学科.
  • 人工智能的人工智能
  • 医疗成像医学成像

背景情况:

  • 骨骨折是常见的手腕损伤,通常很难在最初的X射线图上检测到.
  • 隐形骨折在普通X射线上看不到,这会给诊断带来挑战,如果错过,可能导致并发症.

研究的目的:

  • 开发和评估一种深度学习 (DL) 模型,用于从手腕放射图中检测明显和隐藏的骨骨折.
  • 将DL模型的诊断性能与临床专家小组进行比较.

主要方法:

  • 来自408名患者的1011张手腕放射图的数据集进行了策划,通过先进成像 (MRI/CT) 证实了骨骨折.
  • 在注释图像上训练了基于细分的DL模型,识别了骨和潜在的骨折部位.
  • 对DL模型的性能进行了评估,对比了基本事实和三个骨科专家的解释.

主要成果:

  • DL模型表现出强大的诊断性能,灵敏度为0.86和特异性为0.83.
  • 该模型实现了0.85的整体精度和0.92.9的ROC曲线下的面积.
  • 值得注意的是,DL模型检测到41%的隐形骨折,明显优于专家 (6.8%-13.7%).

结论:

  • 基于细分的DL模型是用于骨骨折检测的可行工具,与现有的DL模型相似.
  • 该DL模型显示性能与专家相提并论的明显骨折和卓越的精度隐藏的骨折.
  • 通过DL模型加强隐藏的骨骨折的检测,可能会改善患者的治疗和治疗结果.
