Abstract
Multidetector CT angiography (CTA) has become a widely accepted examination for non-invasive evaluation of the heart and coronary arteries. Despite its ongoing success and worldwide clinical implementation, it remains an often-challenging procedure in which image quality, and hence diagnostic value, is determined by both technical and patient-related factors. Thorough knowledge of these factors is important to obtain high-quality examinations. In this review, we discuss several key elements that may adversely affect coronary CTA image quality as well as potential measures that can be taken to mitigate their impact. In addition, several recent vendor-specific advances and future directions to improve image quality are discussed.
摘要
多排螺旋CT血管造影（CTA）已成为一种广泛接受的用于心脏和冠状动脉无创评估的检查方法。尽管它不断取得成功并在全球范围内临床应用，但它仍然是一个经常具有挑战性的程序，其中图像质量以及因此的诊断价值由技术和患者相关因素共同决定。全面了解这些因素对于获得高质量的检查很重要。在本综述中，我们讨论了几个可能对冠状动脉CTA图像质量产生不利影响的关键因素，以及可以采取的减轻其影响的潜在措施。此外，还讨论了最近几家供应商的特定进展以及提高图像质量的未来方向。
