Introduction 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.

Aim of Study To present technical background for AWE using T1 SPACE dark blood sequence and our first experiences with AWE imaging.

Methods Using T1 SPACE dark blood sequence pre- and post-gadolinium contrast administration imaging on 3T MR.

Results 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.

Conclusion We successfully implemented new imaging sequence into our routine aneurysm imaging.
