| y | 1 [0.81–1] | 1 [0.91–1] |
| z | 2 [2–2] | 2 [2–2] |
| Reconstructed matrix size | ||
| x | 448 [448–576] | 448 [448–512] |
| y | 448 [448–576] | 448 [448–512] |
| z | 125 [113–125] | 125 [125–125] |
| Repetition time [ms] | 1,300 [1,300–1,400] | 1,400 [1,300–1,400] |
| Echo time [ms] | 87 [61–152] | 150 [60–152] |
| Flip angle [degrees] | 90 [90–90] | 90 [90–90] |
| Number of averages | 2 [2–2] | 2 [2–2] |
| Scan time [s] | 221 [221–283] | 236 [221–283] |
The x, y, and z (cranial–caudal) refer to the imaging axes. The read-out direction was along the x-axis in all acquisitions. Values are given as median [minimum–maximum].
