Article Title: Association between intracranial artery stenosis and aneurysm rupture risk: Proximal stenosis as a potential protective factor
doi: 10.1177/00368504251346013
Figure Lengend Snippet: Some cases of aneurysms and arterial stenosis (A. ruptured internal carotid artery aneurysm combined with parent artery stenosis; B. unruptured middle cerebral artery aneurysm combined with parent artery stenosis; C. ruptured anterior cerebral artery aneurysm combined with middle cerebral artery stenosis) (red arrow: aneurysm; yellow arrow: arterial stenosis) (CTA-3D: the three-dimensional reconstruction results of computed tomography angiography; CT: the scan result of computed tomography).
Article Snippet: Two neuroradiologists, with 12 and 13 years of experience respectively, independently assessed each aneurysm's origin, determined whether it was a bifurcation aneurysm, checked for the presence of a daughter sac, and evaluated for proximal parent artery stenosis using the reconstructed three-dimensional CTA (GE Discovery CT750 HD or GE Revolution CT or Philips iCT 256) datasets.
Techniques: Computed Tomography
