科学领域:

  • 放射学 放射学是一门学科.
  • 在瘤学瘤学.
  • 医疗成像医学成像

背景情况:

  • 扩散权重成像 (DWI) 参数越来越多地被用作癌症诊断和治疗监测中的生物标志物.
  • 不同机构对DWI定量测量的一致性是广泛临床采用的关键,但不确定的因素.

研究的目的:

  • 在多中心环境中,通过多个MRI扫描仪评估DWI衍生的定量指标的一致性.
  • 为了评估表面扩散系数 (ADC) 和内不连贯运动 (IVIM) 参数对于宫癌成像的可靠性.

主要方法:

  • 追溯分析了来自193名宫癌患者的DWI数据,这些数据来自三个中心的四个扫描仪.
  • 使用单指数和IVIM模型处理DWI数据以导出ADC,D,D*,f和fD*参数.
  • 从不同的MRI扫描仪获得的DWI参数的比较分析.

主要成果:

  • 在某些扫描仪之间观察到D和ADC参数的显著差异 (P <0.01).
  • perfusion 参数 (D* 和 fD*) 在所有测试的扫描仪中显示出很高的一致性 (P >0.05).
  • 来自同一厂商和模型的扫描仪显示了ADC和IVIM参数的近距离测量.

结论:

  • 同一个型号和供应商的扫描仪可以提供一致的ADC和IVIM测量.
  • 来自DWI的输液参数在不同的扫描仪中表现出卓越的一致性,这使得它们对宫癌的多中心研究具有前景.
