Acquisition Parameters for MRI sequences used in this study.
| Acquisition | Nominal FA | TR (ms) | TE (ms) | Spatial Resolution (mm) | Interpolated voxel size (mm) |
|---|---|---|---|---|---|
| HASTE | 10° | 489.6/521.4 | 1.16/1.36 | 1.4 × 2.0 × 5 | 1.4 × 1.4 × 5 |
| DCE-MRI | 15° | 4.1 | 1.5 | 1.0 × 2.1 × 2.1 | 1.0 × 1.0 × 1.2 |
| VFA (T1 map) | 5 or 6 FAs (1° to 17°) | 4.9 or 5.1 | 1.9 or 2.5 | 1.0 × 1.1 × 2.11 or 1.0 × 2.1 × 2.0 | 1 × 1 × 1.2 or 1.0 × 1.0 × 1.0. |
| AFI B1 Map | 50° | TR1 = 20 TR2 = 100 | 2.46 | 2.4 × 4.0 × 2.4 | 2.4 × 2.4 × 2.4 |
| SS-Pre B1 Map | 80° | 10,000 | 2.0 | 5.94 × 5.94 × 5 | N/A |
VFA = variable flip angle, AFI B1 = actual flip angle B1 mapping sequence, SS-PRE B1 = slice-selective pre-conditioning RF pulse B1 mapping sequence
