[Diagnostic significance of intravenous digital subtraction angiography of the supra-aortic extracranial vascular system. Comparative study of i.v. DSA and plain film angiography]. / Diagnostische Aussagekraft der intravenösen digitalen Subtraktionsangiographie des supraaortalen extrakraniellen Gefässsystems. Eine vergleichende Studie von i.v. DSA und Blattfilmangiographie.

Digital intravenous subtraction angiography (DSA) and conventional film angiography were used to evaluate the diagnostic reliability of DSA-examinations. In 90% of 650 DSA-angiogramms the image quality was diagnostic. For 124 carotid angiographies a comparison of both methods was possible and gave a sensitivity of 87%, a specificity of 96% and an accuracy of 90% for the DSA examinations. The authors believe that digital subtraction angiography is suitable as a screening method for supraaortal vascular occlusive diseases.
