數字減影血管造影（Digital Subtraction Angiography，DSA）是一種醫學影像技術，通過數字化處理生成高清晰度的血管圖像。其原理分為三步：首先注射含碘造影劑，隨後用X射線設備連續拍攝血管區域圖像，最後通過計算機算法将造影劑到達前後的圖像進行“減影”處理，消除骨骼、軟組織等背景幹擾，保留血管結構的動态影像。
該技術主要應用于心血管疾病診斷（如冠狀動脈狹窄、動脈瘤）和介入治療引導。根據美國心髒協會的臨床指南，DSA在評估腦血管畸形和腫瘤供血動脈方面具有不可替代的精度優勢。最新研究顯示，三維DSA技術通過多角度圖像重建，可将血管空間分辨率提升至0.2毫米級别，顯著提高微小病變檢出率。
相較于傳統血管造影，DSA的輻射劑量降低約40%（根據《放射醫學》期刊數據），但英國國家健康體系仍建議嚴格把控適應症，特别是對腎功能不全患者需謹慎使用造影劑。目前該技術已與人工智能結合，德國海德堡大學醫院的臨床測試表明，AI輔助的DSA系統可将圖像分析時間縮短至傳統方法的1/3。
Digital Subtraction Angiography（DSA）是一種醫學影像技術，中文譯為“數字減影血管造影術”。以下是詳細解釋：
DSA通過兩次成像實現減影：
