科学领域:

  • 生物医学工程 生物医学工程
  • 医疗成像医学成像
  • 整形外科手术 整形外科手术

背景情况:

  • 股骨头骨死 (ONFH) 是一种致残的疾病,导致骨细胞死亡和潜在的关节置换.
  • 早期检测至关重要,但目前的手术内成像,如光学,往往无法识别早期的ONFH病变.
  • 精确地定位死角区域是具有挑战性的,阻碍了及时的手术干预.

研究的目的:

  • 开发和验证一种新的框架,用于定位骨病变,用计算机断层扫描 (CT) 拍摄大腿骨头的图像.
  • 为了使CT中ONFH病变的可视化,弥合MRI诊断和手术内指导之间的差距.
  • 为了研究框架的可行性,将其整合到外科手术工作流程中,用于像ONFH这样的条件.

主要方法:

  • 利用深度学习在MRI扫描中自动细分大腿骨,骨盆和死伤病变.
  • 在CT扫描中对这些解剖学 (不包括死病变) 进行半自动细分.
  • 从MRI和CT中对对注册细分解剖学,以在CT图像中定位死.

主要成果:

  • 该框架成功地在MRI和CT中对解剖结构 (股骨,骨盆) 进行了细分.
  • 实现了对应的解剖体积的准确记录.
  • 证明了在CT中可视化和定位ONFH病变的能力,并生成X射线.

结论:

  • 拟议的框架可以在CT扫描中准确地定位和可视化股骨头骨硬化.
  • 这项技术有可能增强对核心减压等手术的手术内指导.
  • 该框架有助于改善早期ONFH的手术规划和治疗.
