| Objective: To analyze the related features of intracranial aneurysms by high resolution magnetic resonance angiography(high-resolution magnetic resonance vessel wall imaging,HR-MRVWI),and to analyze the relationship between aneurysm wall enhancement signal(aneurysm wall enhancement,AWE)signal,clinical factor and imaging features of intracranial aneurysms.Methods: This study was a retrospective study.Between December 2019 and March 2022,63 patients at the first affiliated Hospital of Xinjiang Medical University,identified by CTA and MRA with intracranial aneurysms,underwent HR-VWI sequence plain scan and enhanced HR-VWI sequence examination.Vessel analysis workstation software was then employed to reconstruct the images and detect if the aneurysm wall enhancement signal was present,as well as to analyze the associated aneurysms’ characteristics.Results: Among the 63 patients with intracranial aneurysms,enhanced signal was found in 33 cases and non-enhanced signal in 30 cases.There was significant difference in cerebrovascular history between the two groups(<0.05).Among the 63 patients with intracranial aneurysms,there were 40 aneurysms in the enhanced group and 49 aneurysms in the non-enhanced group.Compared with non-enhanced aneurysms,the size and shape of enhanced aneurysms were statistically significant(all < 0.05).In 63 patients with aneurysms,the indexes with statistical significance in univariate analysis were taken as independent variables,and the enhancement of aneurysm wall was analyzed by multivariate logistic regression analysis.The results showed that it was a risk factor for aneurysm wall enhancement,while cerebrovascular history,aneurysm location and shape had no effect on aneurysm wall enhancement.Conclusion: HR-VWI analysis of patients with intracranial aneurysms shows that large aneurysms and small aneurysms with ≤ 6.9mm have influence on aneurysm wall enhancement,especially for small aneurysms,the stability of aneurysms can be evaluated by enhanced signals. |
