Table 1 The scanning protocol for the volunteers, breathing patterns and used abbreviations (NB = normal breathing, IB = irregular breathing, aB = after Break) for each scan of the corresponding slice position
From: Ventilation and perfusion MRI at a 0.35 T MR-Linac: feasibility and reproducibility study
Scan | Slice | Breathing pattern | Abbreviation |
|---|---|---|---|
1 | 3D Volume | Breath-hold | 3D-scan |
2 | Aorta | Normal | Reference |
3 | Lung | ||
\(\sim\) 15 min break inside the scanner | |||
4 | Aorta | Normal | NB 2 |
5 | Lung | ||
6 | Aorta | \(\sim\) 25% deeper | IB |
7 | Lung | ||
\(\sim\) 10–20 min break outside the scanner | |||
8 | Aorta | Normal | NB aB 1 |
9 | Lung | ||
\(\sim\) 2–5 min break inside the scanner | |||
10 | Aorta | Normal | NB aB 2 |
