| Delineation of Shape Score* | Rotational DA (n = 28) | MIP 3D DA (n = 28) | SSD 3D DA (n = 28) | Volume-Rendering 3D DA (n = 28) |
|---|---|---|---|---|
| +2 | 16 (57) | 18 (64) | 24 (86) | 27 (96) |
| +1 | 8 (29) | 6 (21) | 4 (14) | 1 (4) |
| 0 | 4 (14) | 4 (14) | 0 (0) | 0 (0) |
| −1 | 0 (0) | 0 (0) | 0 (0) | 0 (0) |
| Mean score ± SD | 1.43 ± 0.74 | 1.50 ± 0.75 | 1.86 ± 0.36 | 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.
