| Delineation of Location Score* | Rotational DA (n = 28) | MIP 3D DA (n = 28) | SSD 3D DA (n = 28) | Volume-Rendering 3D DA (n = 28) |
|---|---|---|---|---|
| +2 | 12 (43) | 21 (75) | 26 (93) | 27 (96) |
| +1 | 10 (36) | 6 (21) | 2 (7) | 1 (4) |
| 0 | 6 (21) | 1 (4) | 0 (0) | 0 (0) |
| −1 | 0 (0) | 0 (0) | 0 (0) | 0 (0) |
| Mean score ± SD | 1.21 ± 0.79 | 1.71 ± 0.54 | 1.93 ± 0.26 | 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.
