Number of discrepancies between sCTA and DSA for both readers
| Intracranial Aneurysm Feature | Discrepancies between sCTA and DSA | Comments | |
|---|---|---|---|
| Reader 1 | Reader 2 | ||
| Aneurysm closure (Raymond 1) | 0 | 0 | NA |
| Complete device deployment | 0 | 1 | Device deployment was scored complete on sCTA but incomplete on DSA; a second reading of this case confirmed complete device deployment on DSA |
| Complete wall apposition | 1 | 1 | In 1 patient, both readers scored wall apposition incomplete on sCTA but complete on DSA; a second reading of this case confirmed incomplete wall apposition on DSA |
| Complete neck coverage | 0 | 0 | NA |
| Vessel patency distal (nonstenotic) | 1 | 0 | Vessel patency was scored nonstenotic on sCTA but stenotic on DSA in 1 case; a second reading confirmed nonstenosis on DSA |
| Vessel patency proximal (nonstenotic) | 0 | 0 | NA |
| Side branch patency (no change) | 0 | 1 | In 1 case, a side branch was missed on follow-up sCTA; a second reading of the case confirmed a patent side branch on sCTA |
