Figure 1. Top row shows the front (left) and lateral views (middle) of 3D DSA and a rendering image (right). Bottom row shows the front (left) and lateral views (middle) of DynaCT images and overlap of basilar tip aneurysm models from DSA and DynaCT images (right). Aneurysm from 3D DSA is in red and aneurysm from DynaCT is in light gray. A large portion of aneurysm from DynaCT is missing in 3D DSA. 3D DSA indicates 3D digital subtraction angiography.
