Sequence block | RF pulse | B1 modulation | G modulation(a) | Tp (ms) |
BW (kHz) |
γB1,max (kHz) |
---|---|---|---|---|---|---|
TOCSY (high-power) | GOIA-W(16,4) | WURST-16 | WURST-4 | 1.25 | 16 | 1.22 |
TOCSY (medium-power) | GOIA-W(16,4) | WURST-16 | WURST-4 | 1.5 | 13.34 | 1.02 |
TOCSY (low-power) (b) | GOIA-W(16,4) | WURST-16 | WURST-4 | 2.0 | 10 | 0.76 |
LASER | GOIA-W(16,4) | WURST-16 | WURST-4 | 3.5 | 20 | 0.82 |
for all pulses an inverse WURST-4 function was used with a gradient reduction factor f = 0.9 in the middle of the pulse;
the condition used for in-vivo MRS.
