Line scan echo planar spectroscopic imaging

A line scan echo planar spectroscopic imaging (LSEPSI) sequence is presente d which can rapidly produce 2D chemical shift imaging (CSI) data with minim al relaxation weighting and motion-related artifacts. The technique is base d on successive "snapshot" 1D CSI acquisitions of individual tissue columns , and avoids T-1 saturation problems associated with the short TR periods n eeded for very rapid scanning with either conventional or echo planar-based 2D CSI methods. Potential applications include rapid fat/water spectral qu antitation in the abdomen and internally referenced temperature monitoring for interventional procedures. (C) 2000 Wiley-Liss, Inc.
