Relationship between 3D Morphologic Change and 2D and 3D Growth of Unruptured Intracranial Aneurysms.

Growing unruptured intracranial aneurysms show morphologic change. However, nearly 10% of nongrowing unruptured intracranial aneurysms change in morphology, suggesting that they could be unstable. Future studies should investigate the best growth definition including morphologic change and size to predict aneurysm rupture.
