Aneurysm Detection Score* | Rotational DA (n = 30) | MIP 3D DA (n = 30) | SSD 3D DA (n = 30) | Volume-Rendering 3D DA (n = 30) |
---|---|---|---|---|
+2 | 24 (80) | 25 (83) | 27 (90) | 29 (97) |
+1 | 4 (13) | 3 (10) | 3 (10) | 1 (3) |
0 | 2 (7) | 2 (7) | 0 (0) | 0 (0) |
−1 | 0 (0) | 0 (0) | 0 (0) | 0 (0) |
Mean score ± SD | 1.73 ± 0.58 | 1.77 ± 0.57 | 1.90 ± 0.31 | 1.97 ± 0.18 |
Note.—Data are number of aneurysms. Numbers in parentheses are percentages.
+2 indicates sufficient visualization; +1, ambiguous visualization; 0, poor visualization; −1, misinterpretation.
