| CE-MRA | Angiography | |||
|---|---|---|---|---|
| Incomplete Occlusion | Adequate Occlusion | Total | ||
| Neck Remnant | Complete Occlusion | |||
| Incomplete occlusion | 9 | 2 | 0 | 11 |
| Adequate occlusion | ||||
| Neck remnant | 2 | 10 | 5 | 17 |

* Correlation for the 3-tier classification was moderate (κ = 0.52; 95% CI, 0.35–0.69) with full agreement in 44 (64%) of 69 aneurysms. Correlation for the 2-tier classification, adequate and incomplete occlusion, was good (κ = 0.74; 95% CI, 0.52–0.96), with a full agreement in 64 (93%) of 69 aneurysms.
