When using parallel imaging accelerated echo planar imaging (EPI), Nyquist ghost correction typically necessitates an additional pre-scan or calibration lines. This work presents a method to perform Nyquist ghost correction in k-space on individual parallel imaging shots using an approached based on the singular value decomposition (SVD) that does not require a complete image or calibration lines. This obviates the standard Nyquist ghost correction pre-scan. A further advantage is that ghost correction can be performed on a shot-by-shot basis, which could be beneficial in the case of calibration drift or prospective motion correction.
