Macroscopic B0 field gradients may result in signal dropouts in gradient echo images obtained at high field, and obscure the information reflecting local tissue structure and composition. While several methods exist to correct for these dropouts, we demonstrate that improved correction is possible with a simple method that better takes into account the effects of in-plane dephasing effects.
