A novel method to induced saturation-transfer-recovery steady states for determining kex with low saturation power, short duration, and hence negligible SAR deposition.
Figure.1 Two
saturation transfer recovery steady-states (STRESS) with different Saturation
powers (B1’s)
Figure.2 A) An iSTRESS MRI pulse
sequence: an excitation RF pulse flips the magnetization by a small flip angle (β) followed by a saturation pulse and signal reading B)
The demonstration of two iSTRESS states under flip angles of 20o and
30o.
