Mechanisms to create a homogenous T₂ contrast at 7T should be robust to both B₀ and B₁ inhomogeneities. This issue was addressed by applying a zero-degree BIR-4 adiabatic pulse for T₂ preparation. Simulation and in vivo experiments in mouse brain verified the robustness and contrast of the preparation scheme at 7T. Application of this method was further demonstrated in a study of a patient with a brain tumor. The adiabatic T₂ weighting showed high intensity in the region of the tumor, suggesting that the proposed method is likely to be useful in screening and characterizing tumors.
