ABSTRACT
Aims: The advent of three-dimensional (3D) rotational angiography (3D DSA) challenged the role digital subtraction (DSA) as a gold standard in diagnosis intracranial aneurysms. In this study, we report our experiences diagnosing aneurysms by using 3D DSA with volume rendering (VR) technique, particularly focusing on its depicting additional missed 2D DSA. Materials and Methods: One hundred thirty-eight consecutive patients known or suspected (54 men, 84 women; median age, 55 years; age range, 18-83 years) underwent both conventional VR examination simultaneously. images were evaluated two observers independently for presence Then decided depicted. Results: showed 146 123 (89.1%) 138 no 15 patients. 115 110 137 patients, one aneurysm 106 each, 2 3 each 1 patient. After reaching consensus, there 31 detected VR. 30 <3 mm maximum diameter ruptured. These located internal carotid artery (ICA, n = 28, 90.32%), anterior cerebral (ACA, 3, 9.68%). No found either middle (MCA) vertebrobasilar posterior (PCA) systems. Conclusions: DSA, especially images, not only clearly reveals aneurysmal morphology, but also detects small less than mm.
