Compensation for Spin-Lock Artifacts Using an Off-Resonance Rotary Echo in T(1)ρ(off)-Weighted Imaging

The origin of image artifacts in an off-resonance spin-locking experiment is shown to be imperfections in the excitation flip angle. A pulse sequence for off-resonance spin locking is implemented that compensates for imperfections in the excitation flip angle through an off-resonance rotary echo. Th...
