The applications of digital subtraction angiography (DSA) in neurologic diagnosis have been evolving as clinical experience with this technology accumulates. Initial enthusiasm with the intravenous contrast material injections has been tempered by often equivocal results. Intravenous DSA (IV-DSA) is still an accurate screening technique for extracranial carotid atherosclerosis, comparable to duplex ultrasound. Intracranial imaging is less satisfying with intravenous injections but reliable information is available in the assessment of the venous sinuses and parasellar internal arteries. The future of DSA lies with intraarterial contrast injections, as this technique substantially decreases the risks and costs of definitive cerebrovascular investigation.
随着数字减影血管造影（DSA）技术临床经验的积累，其在神经科诊断中的应用不断发展。最初对静脉注射造影剂的热情因结果往往不明确而有所降温。静脉DSA（IV-DSA）仍然是一种用于颅外颈动脉粥样硬化的准确筛查技术，与双功超声相当。静脉注射时颅内成像效果欠佳，但在评估静脉窦和鞍旁内部动脉时可获得可靠信息。DSA的未来在于动脉内注射造影剂，因为该技术可大幅降低确定性脑血管检查的风险和成本。
