肺动脉计算机断层扫描血管造影（CTA）已成为评估肺栓塞（PE）的主要诊断测试。这不仅是因为该技术的可用性好、成本低和侵入性小，而且主要是因为多探测器CT技术的引入导致分辨率、速度和图像质量的显著改善。图像采集速度的这种连续增益沿着了新的图像采集技术的引入，如双源CT扫描和超越形态学发现的新的图像解释概念，包括由此产生的灌注缺损的定义和作为功能单元的心肺循环的评估。本文将着重于技术和实践方面，以优化CTPA检查与现代多功能，探测器CT扫描仪，讨论了在特定的患者群体（例如，例如，在一个实施例中，怀孕期间，年轻患者），并概述了新的进展，如双源肺灌注和肺栓塞的自动检测。(C)2010爱思唯尔爱尔兰有限公司版权所有。
Computed tomography angiography (CTA) of the pulmonary arteries has become the main diagnostic test for the evaluation of pulmonary embolism (PE). Not only due to the good availability, low cost and minimal invasiveness of this technique, but mainly because of the introduction of multi-detector CT techniques resulting in significant improvement in resolution, speed and image quality. This continuous gain in image acquisition speed went along with the introduction of new techniques of image acquisition, such as the dual-source CT scanning and novel concepts of image interpretation beyond morphological findings including the definition of the resulting perfusion defects and assessment of the cardiopulmonary circulation as a functional unit.This article will focus on technical and practical aspects to optimize CTPA examinations with modern multi-detector CT scanners, discusses aspects to be considered in specific patient groups (e. g., during pregnancy, young patients) and outlines new advents such as dual-source lung perfusion and automatic detection of pulmonary emboli.
