Fig 1. Computer simulation before stent placement in a superior cerebellar artery aneurysm (same patient as in Fig 2). A, 3D image after automated aneurysm detection (blue) and stent simulation. B, Corresponding graph indicating vessel diameters in segment lengths. Proximal and distal diameters are indicated by D1 (4.2 mm) and D2 (2.5 mm). The aneurysm neck is indicated by the bidirectional arrow. Use of a 37-mm stent will provide a proximal and distal overlap of 10 mm.
