Rapid Frequency Offset Mapping with the Half-Fourier Acquisition Single-Shot Turbo Spin-Echo with the Selective Parity Approach

Frequency Offset maps are widely used to correct image distortion or estimate signal loss in gradient echo signal due to field inhomogeneities. Routinely, multiecho gradient echo sequences are used to collect this information. In this work, we introduce an innovative method which enables frequency offset mapping via one single-shot acquisition. The proposed method offers a significant reduction in the acquisition time without loss of accuracy.
