强化光相干断层扫描血管成像检查图像采集质量与报告规范，提升其临床应用研究水平

Enhance the quality of image acquisition, reporting and interpreting, and clinical application of optical coherence tomography angiography

光相干断层扫描血管成像（OCTA）是一无创实时检测视网膜脉络膜血流形态的新技术，了解其技术原理，充分认识影~OCTA图像采集与结果判读的多种因素，在图像采集以及分析判读过程中，注意OCTA图像的分层判定、OCTA血流信号分析判读以及OCTA成像伪迹辨识，进一步强化OCTA图像采集质量与报告规范，才能切实推动OCTA临床应用研究水平的不断提高，从而更好地利用该技术，为眼底疾病诊断治疗提供更精准的特征信息，提升眼底疾病的认知和治疗水平。

Optical coherence tomography angiography （OCTA） is a new and nonlnvaslve imaging technique that generates real-time blood flow pattern on chorioretinal vasculature. In order to apply this novel technology in the practice to diagnose and treat ocular fundus diseases, we need to further strengthen the quality of OCTA image acquisition and reporting specifications. We need to understand its technical principle, and multiple factors affecting the OCTA image acquisition and interpretation. Furthermore, In the process of image acquisition, as well as analysis and interpretation, we need to pay attention to the stratification, interpretation of blood flow signals and identification of artifacts of OCTA images.
