Abstract

A motion artifact reduction method for proton chemical shift imaging (CSI) is presented. The method uses spiral-based read-out gradients for data acquisition. A characteristic of spiral-based readout gradients is that data are repeatedly sampled at the kxy origin. These data points are used to estimate and correct for motion-induced phase variations. Both phantom and in vivo spectra reconstructed using the new motion artifact reduction algorithm showed significant signal-to-noise ratio (SNR) improvements as compared to uncorrected data.
