| Delineation of Neck Score* | Rotational DA (n = 28) | MIP 3D DA (n = 28) | SSD 3D DA (n = 28) | Volume-Rendering 3D DA (n = 28) |
|---|---|---|---|---|
| +2 | 17 (61) | 23 (82) | 21 (75) | 27 (96) |
| +1 | 7 (25) | 3 (10) | 4 (14) | 1 (4) |
| 0 | 4 (14) | 1 (4) | 2 (7) | 0 (0) |
| −1 | 0 (0) | 1 (4) | 1 (4) | 0 (0) |
| Mean score ± SD | 1.46 ± 0.74 | 1.71 ± 0.71 | 1.61 ± 0.79 | 1.96 ± 0.19 |
Note.—Data are number of aneurysms. Numbers in parentheses are percentages.
*
+2 indicates sufficient visualization; +1, ambiguous visualization; 0, poor visualization; −1, misinterpretation.
