BACKGROUND AND PURPOSE:
Previous studies have shown that intracranial aneurysm wall enhancement (AWE) is associated with aneurysm growth or rupture. These studies assessed growth with manual 2D measurements or eyeballing, both of which are prone to interobserver variability. To minimize this variability, we assessed the association between AWE and semiautomatically quantified 3D morphologic changes in aneurysms during long-term follow-up.
MATERIALS AND METHODS:
We included patients with an unru…
