A Prospective Follow-up Study on Risk Factors to Predict the Progression of Unruptured Intracranial Aneurysms on Enhanced HR-MRI.

Rationale And Objectives: To prospectively investigate the potential correlation between qualitative and quantitative assessment of aneurysm wall enhancement (AWE) on initial enhanced high-resolution magnetic resonance imaging (HR-MRI) and aneurysm progression during follow-up.

Materials And Methods: From June 2016 to January 2021, we prospectively recruited patients with unruptured intracranial aneurysms (UIAs) for enhanced HR-MRI examination. The patients' demographic and clinical data and aneurysm characteristics, including AWE features, were collected and analyzed.
