Abstract
In an MR spectroscopy method nuclear magnetization of a plurality of voxels present at an area of intersection of two slices is simultaneously excited by repeated sequences, the resultant phase encoding of the voxels is varied from one sequence to another, and a spectral distribution of nuclear magnetization in the voxels is derived from linear combinations of the MR signals generated in the individual sequences. A method is obtained wherein each sequence a first slice-selective RF pulse is generated in order to excite the transverse magnetization in one or more first slices, and subsequently a second slice-selective RF pulse is generated in order to refocus nuclear magnetization in one or more second slices which intersect the first slices at an angle other than zero, and in the various sequences the MR signals produced by the spin echos in the voxels present at the area of intersection of each first and second slice is detected and used to determine the spectral distribution of the nuclear magnetization.
