Evaluation for the depiction of simulated aneurysms (I.I.-TV system vs FPD system)
| Contrast Material Concentration & System | Score for Image Quality | Mean ± SD | P* | ||||
|---|---|---|---|---|---|---|---|
| 5 | 4 | 3 | 2 | 1 | |||
| 300 mg I/mL | |||||||
| FPD (n = 20) | 10 | 3 | 5 | 2 | 0 | 4.05 ± 1.10 | <.01 |
| I.I. (n = 20) | 3 | 4 | 6 | 4 | 3 | 3.00 ± 1.27 | |
| 150 mg I/mL | |||||||
| FPD (n = 21) | 3 | 10 | 4 | 2 | 2 | 3.48 ± 1.14 | <.01 |
| I.I. (n = 21) | 1 | 5 | 3 | 7 | 5 | 2.52 ± 1.20 | |
Note:—FPD indicates flat panel detector; I.I., image intensifier. Scale: 5, excellent; 4, more than adequate; 3, adequate; 2, insufficient visualization; 1, not visible.
