Image Contrast Enhancement using Selective Adiabatic Pulses that Alternate Frequency Sweep Directions

magnitude (Mxy/M0) generated by AFPSFS/AFS pulse trains as a function of RF offset Figure 2. Contrast generated by AFP-SFS/AFS pulse trains as a function of TE for the phantom. Figure 3. Phantom and mouse brain images collected using AFP-SFS-SE (A, C) and AFP-AFS-SE (B, D) pulse sequences at TE = 80 ms (A, B) and TE = 49 ms (C, D).
