## Abstract One primary disadvantage of spiral imaging is blurring artifact due to offβresonance effects. The conventional frequency segmented offβresonance correction method that is performed over the entire image is computationally intense due to the large number of fast Fourier transforms (FFTs)

Partial volume effects with cerebrospinal fluid (CSF), if uncorrected, can lead to underestimation of metabolite concentrations in quantitative proton magnetic resonance spectroscopic imaging (MRSI) of the brain. A rapid method for the correction of CSF partial volume effects is described based on s
## Abstract Field inhomogeneity and susceptibility variations, coupled with a long readout, can result in image blurring in spiral imaging. Many correction methods based on a priori offβresonance information, such as an acquired field map, have been proposed in the literature. Automatic offβresonan
