摘要

目的:探讨时间期相在多层螺旋CT（Multislice CT

MSCT）肝脏增强扫描中的特殊应用价值。方法:回顾性分析143例肝脏增强扫描病例的不同扫描时间期相与其图像特征之间的对应关系。结果:肝脏增强扫描的时间期相可以分为:肝动脉早期、肝动脉中期、肝动脉晚期、门静脉期、门静脉-肝静脉期、肝静脉期及延迟期。结论:多层螺旋CT肝脏增强扫描时

不同的时间期相有其各自的图像特征和特殊应用价值

应根据肝脏增强扫描目的不同而加以区别对待和应用。

Abstract

Objective:To study the special values of the time phases in liver enhancement scanning with multi-slices helical CT.Methods:The relationship between the image features and the time phases was retrospectively analyzed with 143 cases that underwent liver enhancement scanning with multi-slices helical CT.Results:The time phases of liver enhancement scanning included hepatic artery earlier phase

hepatic artery metaphase

hepatic artery advanced phase

hepatic portal venous phase

hepatic portal venous-hepatic venous phase

hepatic venous phase and lag period.Conclusion:The different image features have the special value in the different time phases when liver was scanned with multi-slices helical CT.They ought to be differently treated and used according to the different objectives of liver enhancement scanning.
