“…To the best of our knowledge, there are only three published papers investigating post-procedural aneurysm contrast enhancement on HR-VW MRI [28][29][30]. The reported frequency of post-procedural aneurysm contrast enhancement on HR-VW MRI in the published papers is comparable with our study.…”

“…Songsaeng et al also did not find any statistically significant association [30]. Time between aneurysm embolization and HR-VW MRI varies substantially between studies, which could have led to discrepancies in their results [28][29][30]. For instance, the median follow-up period in the study by Larsen et al was approximately three times shorter than that reported by Songsaeng et al [28,30].…”

“…As in our study, Elsheikh et al did not demonstrate any relationship between post-procedural aneurysm contrast enhancement and time elapsed since embolization. Songsaeng et al also did not find any statistically significant association [30]. Time between aneurysm embolization and HR-VW MRI varies substantially between studies, which could have led to discrepancies in their results [28][29][30].…”

“…Time between aneurysm embolization and HR-VW MRI varies substantially between studies, which could have led to discrepancies in their results [28][29][30]. For instance, the median follow-up period in the study by Larsen et al was approximately three times shorter than that reported by Songsaeng et al [28,30]. Moreover, there is a significant disproportion in the published literature between the relatively small number of investigated aneurysms and a wide range of time intervals between aneurysm embolization and HR-VW MRI.…”

“…Thus, we believe that research on the use of HR-VW MRI in patients with intracranial aneurysm should not be restricted to AWE and prediction of aneurysm rupture but other applications of this imaging tool should also be investigated. While there is growing evidence for the use of HR-VW MRI in therapeutic decision making in patients with UIA, the possible clinical significance of post-procedural aneurysm contrast enhancement has not been widely studied, with only a few papers published [28][29][30].…”

(1) Background: The aim of this study was to determine the frequency and the pattern of post-procedural intracranial aneurysm contrast enhancement on high-resolution vessel wall magnetic resonance imaging (HR-VW MRI). We investigated the possible association between this imaging finding and factors such as time elapsed since embolization or aneurysm occlusion grade on baseline and follow-up imaging. (2) Methods: Consecutive patients presenting for follow-up after endovascular treatment of intracranial aneurysms were included. HR-VW MRI was acquired and interpreted independently by two radiologists. (3) Results: This study included 40 aneurysms in 39 patients. Contrast enhancement was detected in 30 (75%) aneurysms. It was peripheral in 12 (30.0%), central in 9 (22.5%), and both peripheral and central in 9 (22.5%) aneurysms. The statistical analysis did not reveal any relationship between follow-up period and the presence of contrast enhancement (p = 0.277). There were no statistically significant differences in the frequency of contrast enhancement between aneurysms with total occlusion and those with remnant flow on follow-up MR angiography (p = 0.850) nor between aneurysms with different interval changes in the aneurysm occlusion grade (p = 0.536). Multivariate analysis did not demonstrate aneurysm size, ruptured aneurysm status, nor initial complete aneurysm occlusion to be a predictor of contrast enhancement (p = 0.080). (4) Conclusions: Post-procedural aneurysm contrast enhancement is a common imaging finding on HR-VW MRI. The clinical utility of this imaging finding, especially in the prediction of aneurysm recurrence, seems limited. The results of our study do not support routine use of HR-VW MRI in the follow-up of patients after endovascular treatment of intracranial aneurysms.

BACKGROUND AND PURPOSE: Wall enhancement of untreated intracranial aneurysms on MR imaging is thought to predict aneurysm instability. Wall enhancement or enhancement of the aneurysm cavity in coiled intracranial aneurysms is discussed controversially in the literature regarding potential healing mechanisms or adverse inflammatory reactions. Our aim was to compare the occurrence of aneurysm wall enhancement and cavity enhancement between completely occluded intracranial aneurysms and recanalized aneurysms after initially complete coil embolization.
