The present study describes a model-based approach for correcting off-resonance in the context of short echo-time imaging using a double half-echo k-space acquisition. This technique employs center-out readouts in forward and reverse directions and is sensitive to off-resonance. The correction is simple and results in a marked reduction in blurring for a negligble cost in pre-processing.
