Recommended clipping strategy * after presenting conventional CTA images (2D and screen 3D) or reconstructed 3D-VR images, evaluated using Fisher’s exact test, assuming a p-value <0.05 to be significant.
| Recommendations, n (%) | CTA (n = 260) | 3D-VR (n = 260) | p-Value |
|---|---|---|---|
| temporary clipping: | |||
| yes | 74 (28) | 63 (24) | 0.32 |
| no | 186 (72) | 197 (76) | (not significant) |
| type of permanent clip: | |||
| straight/curved | 175 (67) | 185 (71) | 0.54 |
| angled | 77 (30) | 70 (27) | (not significant) |
| fenestrated | 8 (3) | 5 (2) |
* Based on the questionnaire in Table 1. 2D, two-dimensional; 3D, three-dimensional; CTA, computed tomography angiography; VR, virtual reality.
