Abstract

Three dimensional angio (3D-Angio) is indispensable in neuroradiology, especially for examinations and interventions of cerebral-aneurysms. 3D-Angio has two modes, 3D-DSA and 3D-DA. The former mode is used to determine vessel structures in detail, and the latter is good at simultaneously determining relationships between vascular and osseous structures. However, it is sometimes difficult to determine these relationships with 3D-Angio if they are close together. The relationship between the skull base and adjacent aneurysm is an essential factor in determining treatment strategy. In order to make this determination, we have developed the Bone Fusion function, which reconstructs vessel and osseous structures separately from rotational DSA data and its mask sequence data, respectively, and two independent 3D data sets are fused in one 3D representation. There are three display modes: fusion, vessel only, and bone only, and those structures are clearly identified by different colors on the fusion images. The Bone Fusion function was applied to hundreds of clinical cases in which 3D-DSA and 3D-DA were used. The Bone Fusion provided important information to determine treatment strategy, although those factors were sometimes lost with 3D-DSA and 3D-DA when the studied vasculatures were adjacent to bone. It was especially useful to apply the Bone Fusion function to aneurysms or tumors adjacent to the skull base.
