Coronary CT angiography is a rapidly growing technique that offers distinct advantages over traditional imaging techniques. However, because of rapid growth of this technique, radiation dose safety has been placed under the spotlight. There are several main determinants of total radiation dose, and these are outlined in this review. Integration of these dose-saving techniques will go a long way in maintaining diagnostic image quality and improving patient safety.
冠状动脉 CT 血管造影是一种快速发展的技术，与传统成像技术相比具有明显优势。然而，由于该技术的快速发展，辐射剂量安全性已成为关注焦点。总辐射剂量有几个主要决定因素，本文对此进行了概述。整合这些节省剂量的技术将大大有助于维持诊断图像质量和提高患者安全性。
