Table 2.
Examples of scan parameters with restrictive SAR.
| Sequence | Case | Nsl | RPE | Rsms | TE (ms) | TR (ms) | SAR (%) Fat. Sup. ON | SAR (%) Fat. Sup. OFF |
|---|---|---|---|---|---|---|---|---|
| Ep2d_bold (Siemens product) 1.6 mm iso, flip angle = 90 | 1 | 64 | 3 | 2 | 20 (partial Fourier = 7/8) | 1500 | 101 | 34 |
| 2 | 60 | 3 | 2 | 21 | 1500 | 97 | 33 | |
| 3 | 76 | 3 | 2 | 21 | 1500 | * | 35 | |
| cmrr_mbep2d_bold 1.4 mm iso, RF excitation pulse duration = 4 ms, flip angle 90 | 4 | 78 | 3 | 2 | 22.6 | 2030 | 141 | 80 |
| 5 | 78 | 3 | 3 | 22.6 | 2000 | 101 | 59 |
*This case could not be acquired with TR shorter than 1860 ms (because of the extra time required for the fat suppression pulses)’.
The reference amplitude for 1 ms 180° hard pulse: 240 V.
