数字减影血管造影（Digital Subtraction Angiography，DSA）是一种医学影像技术，通过数字化处理生成高清晰度的血管图像。其原理分为三步：首先注射含碘造影剂，随后用X射线设备连续拍摄血管区域图像，最后通过计算机算法将造影剂到达前后的图像进行“减影”处理，消除骨骼、软组织等背景干扰，保留血管结构的动态影像。
该技术主要应用于心血管疾病诊断（如冠状动脉狭窄、动脉瘤）和介入治疗引导。根据美国心脏协会的临床指南，DSA在评估脑血管畸形和肿瘤供血动脉方面具有不可替代的精度优势。最新研究显示，三维DSA技术通过多角度图像重建，可将血管空间分辨率提升至0.2毫米级别，显著提高微小病变检出率。
相较于传统血管造影，DSA的辐射剂量降低约40%（根据《放射医学》期刊数据），但英国国家健康体系仍建议严格把控适应症，特别是对肾功能不全患者需谨慎使用造影剂。目前该技术已与人工智能结合，德国海德堡大学医院的临床测试表明，AI辅助的DSA系统可将图像分析时间缩短至传统方法的1/3。
Digital Subtraction Angiography（DSA）是一种医学影像技术，中文译为“数字减影血管造影术”。以下是详细解释：
DSA通过两次成像实现减影：
