| 中文摘要: |
| 随着对CT辐射剂量及对比剂肾病认识的不断重视，近年来"双低"CTA扫描技术被逐步应用并成为研究热点。"双低"CTA技术旨在保证影像质量满足诊断需求的前提下，降低受检者X线辐射剂量和碘摄入量。本文针对"双低"概念的提出、基本原理、扫描技术规范和临床应用现状进行综述。 |
| 英文摘要: |
| With the attention to CT radiation and contrast-induced nephropathy, the technology of "double low" CTA has been gradually applied in clinical practice and become a research hotspot in recent years. The "double low" CTA technology aims to reduce X-ray dose and iodine intake of subject in ensuring image quality to meet the diagnostic requirements. The concept of "double low", basic principles, scanning standard protocols and current status of clinical application of "double low" were reviewed in this paper. |
