CEST imaging at 9.4 T using adjusted adiabatic spin‐lock pulses for on‐ and off‐resonant T1⍴‐dominated Z‐spectrum acquisition

Purpose The CEST experiment, with its correlation to rare proton species that are in exchange with the water pool, is very similar to the off‐resonant water spin‐lock (SL) experiment. In particular, low‐power SL Z‐spectrum acquisition allows insight into T 1ρ and exchange effects with decreased direct water saturation. Because the available SL methods either require high B 1 power or are instable in the presence of strong B 1 and B 0...
