Signal-intensity analysis of aneurysm thrombus: signal intensities normalized to braina
| Tissue | T1-Weighted | T2-Weighted | Steady-State |
|---|---|---|---|
| Thrombus core | 1.1 ± 0.3 | 0.6 ± 0.3 | 1.1 ± 0.3 |
| Thrombus rim | 1.5 ± 0.2 | 0.6 ± 0.2 | 2.3 ± 0.3 |
| Blood | 1.0 ± 0.3 | 1.4 ± 0.8 | 4.3 ± 1.7 |
| CSF | 0.5 ± 0.1 | 3.6 ± 0.2 | 7.2 ± 0.9 |
a Thrombus heterogeneity with a rim evident occurred in 4/9 subjects.
