A Study on the Correlation Between Cotinine Levels and Aneurysm Wall Enhancement on HRMRI.

This study aims to explore the relationship between cotinine levels and the risk of intracranial aneurysm rupture by collecting imaging features and patient cotinine levels of unruptured intracranial aneurysms on high-resolution magnetic resonance imaging, combined with the prognosis of patients with aneurysms. Previous studies have shown that the risk of intracranial aneurysm rupture in patients is related to the enhancement of the aneurysm wall on high-resolution magnetic resonance imaging. Therefore, this study included patients who met the inclusion criteria for high-resolution magnetic resonance imaging and cotinine testing, and followed up on the imaging characteristics, prognostic scores, and aneurysm occlusion rate of arterial aneurysms in patients.
