Primary
| Measure | Time frame |
|---|---|
| Number of occult endoleaks only detected at late MR after positional change of the patients Endoleaks will be graded on a 5-point scale (no endoleak, possibly endoleak, probably endoleak, definitely endoleak, not diagnostic). | — |
Secondary
| Measure | Time frame |
|---|---|
| Number of occult endoleaks detected by - delayed CT - dynamic MRA - dynamic MRA + MRA delay 1 - MRA delay 2 - T1-w postcontrast spin echo images (delay 1) - T1-w postcontrast spin echo images (delay 2) • Number of endoleaks detected by - static MRA (first-pass) - MRA delay 1 - MRA delay 2 • Thrombus enhancement • Change in reader confidence for the detection of endoleaks | — |
