Overview of the 3 different sequences used to image volume pulsation and the main results
| Sequence | Stage I TFE | Stage II |
|
|---|---|---|---|
| Improved TFE | CE-Improved TFE | ||
| No. of phases in the cardiac cycle | 15 | 18 | 18 |
| No. of patients included | 9 | 9 | 8a |
| No. of aneurysms included | 10 | 9 | 8a |
| Mean size of the aneurysms (SD, range) (mm) | 9 (4, 3–19) | 8 (4, 2–14) | 8 (4, 2–14) |
| Mean aneurysm volume change (SD, range) (mm3) | 15 (14, 3–51) | 38 (31, 2–88) | 14 (9, 1–25) |
| Mean volume pulsation (SD, range) (%) | 8 (7, 2–27) | 39 (24, 14–73) | 15 (11, 4–36) |
| Mean absolute observed artifactual pulsation (SD, range) (mm3) | 2 (2, 0–5) | – | 13 (9, 1–27) |
Note:—CE indicates contrast-enhanced.
