Restoration of motion-related signal loss and line-shape deterioration of proton MR spectra using the residual water as intrinsic reference.

A postprocessing method to restore motion-related signal loss and line-shape deterioration in single-volume proton MR spectroscopy (MRS) is presented. Each acquisition is corrected by its phase offset and frequency shift, extracted from the residual water signal prior to averaging. Requirements are good gradient selection and selective suppression of CSF in… CONTINUE READING
