The score of depictions of aneurysm and parent artery (1, not visible; 2, poor; 3, good; 4, excellent) with TOF-MRA and CE-MRA were compared with DSA. And sensitivity and specificity of depictions of aneurysm and parent artery with TOF-MRA and CE-MRA were calculated. <h3>Results</h3> The score of CE-MRA (3.632 ± 0.607) was higher than that of TOF-MRA (1.737 ± 0.496; P < 0.001), but the score of CE-MRA with narrow parent arteries (≦ 2.6 mm) was low (1.667 ± 0.745). Sensitivity and specificity with CE-MRA were also higher than those with TOF-MRA. <h3>Conclusion</h3> For the follow-up after coiling with ES, evaluation with CE-MRA is necessary, but in case with narrow parent arteries ( ≤2.6 mm) may be difficult. <h3>Disclosures</h3> K.
