SI measurement | <7 mm (n=17) | ≥7 mm (n=8) | P-value* |
CAWE | 0.24±0.21 | 0.38±0.29 | 0.15 |
3 mm PVE | 0.21±0.28 | 0.24±0.19 | 0.37 |
5 mm PVE | 0.19±0.16 | 0.23±0.18 | 0.59 |
RVE | 0.20±0.18 | 0.16±0.11 | 0.84 |
Values are presented as mean±SD unless otherwise indicated.
*Mann–Whitney U tests were used to calculate P-values due to non-normally distributed data.
CAWE, circumferential aneurysmal wall enhancement; PVE, parent vessel enhancement; RVE, reference vessel enhancement; SI, signal intensity.
