P178 Aneurysm wall enhancement MR imaging on 3T MR – our experiences

<h3>Introduction</h3> Aneurysm wall enhancement (AWE) of unruptured intracranial aneurysms on magnetic resonance imaging has been considered as a promising marker of rupture-related risk. Recently, we have started using T1 SPACE fat-sat dark blood sequence with isotropic voxel to visually evaluate AWE on 3T MR. <h3>Aim of Study</h3> To present technical background for AWE using T1 SPACE dark blood sequence and our first experiences with AWE imaging. <h3>Methods</h3> Using T1 SPACE dark blood sequence pre- and post-gadolinium contrast administration imaging on 3T MR. <h3>Results</h3> From March to half of August 2024, 16 patients (3 men, 13 women, mean age 60±12) were imaged. We observed AWE in 10 patients. <h3>Conclusion</h3> We successfully implemented new imaging sequence into our routine aneurysm imaging.
