Artifacts in T1ρ-Weighted Imaging: Compensation for B(1) and B(0) Field Imperfections

The origin of spin locking image artifacts in the presence of B(0) and B(1) magnetic field imperfections is shown theoretically using the Bloch equations and experimentally at low (ω(1) ≪ Δω(0)), intermediate (ω(1) ~ Δω(0)) and high (ω(1) ≫ Δω(0)) spin locking field strengths. At low spin locking fi...
