DSA is a promising method for improving the results of cerebrovascular angiography. Experience suggests that VI-DSA will have a more limited application than was originally expected. It is a low-risk, cost-efficient technique for serial and postoperative studies and for screening outpatients who may have occlusive extracranial lesions that have not been detected by noninvasive tests; however, false-negative results may be obtained. AI-DSA provides far more accurate and reliable results than VI-DSA and has the potential for increasing the flexibility, efficiency, and safety of angiography, in comparison with conventional techniques.
数字减影血管造影（DSA）是一种有望改善脑血管造影结果的方法。经验表明，静脉数字减影血管造影（VI-DSA）的应用范围将比最初预期的更为有限。它是一种用于系列研究和术后研究以及筛查无创检查未发现的可能患有颅外闭塞性病变的门诊患者的低风险、成本效益高的技术；然而，可能会出现假阴性结果。与传统技术相比，动脉数字减影血管造影（AI-DSA）提供的结果比VI-DSA更准确可靠，并且有可能提高血管造影的灵活性、效率和安全性。
