Abstract

The introduction of multi-detector row computed tomography (MDCT) scanners in 1998 ushered in new advances in CT angiography (CTA). The subsequent expansion of MDCT scanner capabilities, coupled with advances in understanding of contrast medium (CM) dynamics, has further improved the clinical availability and consistency of CTA. We will review recent advances in CT scanner technology and discuss early CM dynamics. Specifically, we describe an approach tailored to the available scanner technology and to patient size aimed at providing consistently robust CTA studies across all vascular territories. A rational method to design combined CTA scan/injection protocols to facilitate this goal will be described. Our current experience with a simplified protocol for CTA with 64-MDCT will also be explained.

摘要

1998年多排螺旋计算机断层扫描（MDCT）扫描仪的引入开创了CT血管造影（CTA）的新进展。随后MDCT扫描仪功能的扩展，再加上对造影剂（CM）动力学认识的进步，进一步提高了CTA的临床可用性和一致性。我们将回顾CT扫描仪技术的最新进展并讨论早期造影剂动力学。具体而言，我们描述了一种针对现有扫描仪技术和患者体型量身定制的方法，旨在在所有血管区域提供始终如一的高质量CTA研究。将介绍一种合理的方法来设计联合CTA扫描/注射方案以实现这一目标。还将解释我们目前使用64排MDCT进行CTA简化方案的经验。
