Susceptibility effect on gradient recalled-echo MR images and clinical thrombus age
Clinical Thrombus Age | SE+ n (%) | SE− n (%) | Total |
---|---|---|---|
0–7 days | 29 (80.5%) | 3 (11.5%) | 32 |
8–14 days | 1 (2.8%) | 10 (38.5%) | 11 |
>15 days | 6 (16.7%) | 13 (50%) | 19 |
Total | 36 | 26 | 62 |
Note:—SE+ indicates susceptibility effect present; SE−, susceptibility effect absent. Accurate time from onset of symptoms to initial imaging (clinical thrombus age) was available in 16 patients (62 thrombosed venous segments).
