多层螺旋CT的原理及临床应用

Principles and Clinical Applications of Multi-slice CT

多层螺旋CT代表CT 发展史上的一个新的里程碑。相对于单层CT而言,它具有扫描速度快,扫描范围广、长轴分辨力和时间分辨力高的优点。它的问世极大地丰富了CT的应用范围,提高了诊断水平。本文概述了多层螺旋CT的基本原理、技术特性和临床应用。

Multi-slice helical CT(MSCT) ope ned a new era in the history of CT development. In comparison with singie slice CT, it has much faster scanning speed, broader scanning scope and higher longitudinal resolution and temporal resolution The advent of MSCT has greatly riched the application scope of CT and improved its diagnostic ability. This article reviewed the basie principles.characleristics and possible applicatiions of MSCT.
