冠状动脉CT血管成像(CTA)的质量受到很多因素的影响,其中至关重要的是造影剂。实现低辐射剂量、良好的图像质量的个性化扫描最重要的影响因素是碘造影剂的身体损害和经济负担,减少造影剂造成的伪影等~([1])。本项研究旨在寻找最佳的造影剂个性化应用方案,最大限度提高图像质量,安全、科学应用造影剂,避免造影剂使用不当给患者身体造成不良影响甚至生命危险,为临床合理使用造影剂提供参考依据。
The quality of coronary CT angiography (CTA) is influenced by many factors, the most important of which are contrast agents. The most important influencing factors for personalized scanning with low radiation dose and good image quality are the physical damage and economic burden of iodine contrast agents and the reduction of artifacts caused by contrast media [1]. This study aims to find the best contrast agent personalized application program to maximize image quality, safety, scientific application of contrast agent, to avoid improper use of contrast agent to the patient’s body caused by adverse effects and even life-threatening, for the clinical rational use of contrast agent Provide a reference basis.
