BRIEF/TECHNICAL REPORT INTERVENTIONAL Arterial and Venous 3D Fusion AV-3D-DSA: A Novel Approach to Cerebrovascular Neuroimaging E. Raz, M. Shapiro, O. Mir, E. Nossek, and P.K. Nelson ABSTRACT SUMMARY: DSA is the standard imaging technique for evaluation of cerebrovascular conditions. However, One drawback is its limi- tation in depicting a single angiographic phase at a time. We describe a new 3D-DSA algorithm, which we call arterial and venous- 3D-DSA, which allows the concurrent yet distinct display of the arterial and venous structures, which may be useful for different clinical and educational purposes.
