A water suppression (WS) technique for diffusion-weighted line-scan echo-planar spectroscopic imaging (DW-LSEPSI) is presented. DW-LSEPSI uses a single chemical shift selective (CHESS) pulse for WS at each acquisition of a line suitable for a short acquisition time and to reduce a water signal using a steady state effect. The signal attenuation of the water signal is numerically analyzed and demonstrated by applying this technique to phantoms and a rat brain in vivo.
