科学领域:

  • 医疗成像医学成像
  • 扩散加权成像是一种扩散加权成像.
  • 磁共振成像是一种磁共振成像技术.

背景情况:

  • 多镜头回声平面成像 (MS-EPI) 容易发生运动诱导的相变化和别名化工件.
  • 这些文物可能会影响扩散指标的准确性,例如平均扩散率 (MD) 和异位变异率 (FA) 分数.

研究的目的:

  • 评估运动补偿扩散编码波形和MS-EPI与钥匙孔 (MS-EPIK) 轨迹,以减少MS-EPI中的工件.
  • 为了比较不同运动补偿命令 (M0,M0M1,M0M1M2) 和轨迹与单射EPI (SS-EPI) 的性能.

主要方法:

  • 使用SS-EPI,MS-EPI和MS-EPIK获得脑,肝脏和心脏中的体内3T数据.
  • 应用非运动补偿 (M0),第一阶段 (M0M1) 和第一和第二阶段 (M0M1M2) 运动补偿扩散编码波形.
  • 分析大脑/心脏中的MD和FA,以及肝脏中的明显扩散系数 (ADC).

主要成果:

  • 在使用M0M1M2波形的SS-EPI,MS-EPIK和MS-EPI之间,在脑白和灰质中没有发现MD/FA的显著差异.
  • 在所有波形中观察到SS-EPI和MS-EPIK之间的肝脏ADC的统计差异,以及使用M0M1M2.2.的MS-EPI.
  • 与MS-EPI相比,MS-EPIK表现出较少的别名,但仍然容易受到扭曲.

结论:

  • 运动补偿波形M0M1M2是减轻MS-EPI在各种器官中射击到射击相位变化的最佳方式.
  • 与标准MS-EPI相比,MS-EPIK轨迹提供了更好的别名减速.
  • 先进的运动补偿和轨迹设计对于提高MS-EPI序列中的DWI精度至关重要.
