On high-field scanners, strong imaging gradients induce spurious diffusion signal decay, which distorts qT2 calculation. By modeling the pulse sequence gradients and coherence pathways, an effective b value was calculated to assess signal attenuation caused by diffusion. ADC values were measured, extensive phantom scans and in-vivo experiments were performed using the MSME protocol with varied voxel sizes to examine the effect and the solution. Before correction T2 values were short with high variability across different voxel sizes, after correction T2 values increased and became more accurate and consistent. Tissue properties also influenced the correction as their ADC varies.
