* Intermodality agreement for the 3-tier classification was good (κ = 0.71; 95% CI, 0.57–0.85) with full agreement in 54 (78%) of the 69 aneurysms. Intermodality agreement for the 2-tier classification, adequate and incomplete occlusion, was very good (κ = 0.83; 95% CI, 0.65–1.00), with full agreement in 66 (96%) of the 69 aneurysms.
