Focal Aneurysm Wall Enhancement in Vessel Wall Imaging as a Surrogate Marker for Predicting Aneurysm Instability.

ABSTRACT:

Background

The establishment of a risk stratification method for unruptured intracranial aneurysms (UIAs) remains an interdisciplinary challenge. The present study attempted to identify unstable UIAs using magnetic resonance vessel wall imaging in prospective data sets. Hemodynamic parameters in unstable UIAs were also examined to clarify the mechanisms by which segmented aneurysm wall enhancement (AWE) affects longitudinal morphological changes.

Methods

Patients with UIAs who underwent contrast-enhanced vessel wall imaging between 2017 and 2022 and were followed up for more than 6 months were included. Two readers independently rated AWE patterns (no, focal, and circumferential AWE) on vessel wall imaging and morphological changes on time-of-flight magnetic resonance angiog
