Dynamic field map estimation using a spiral-in/spiral-out acquisition

The long readout times of single‐shot acquisitions and the high field strengths desired for functional MRI (fMRI) using blood oxygenation level‐dependent (BOLD) contrast make functional scans sensitive to magnetic field inhomogeneity. If it is not corrected during image reconstruction, field inhomog...
