1. A method for acquiring, with a reduced sensitivity to localization artifacts, an NMR spectroscopy response signal from a portion of a sample in a desired voxel located at the intersection of three different surfaces, comprising the steps of: (a) immersing the sample in a static magnetic field B.sub.o ; (b) exciting nuclear magnetic resonance in the sample with a localization subsequence which selectively differentiates NMR signals in only two of the three surfaces; and (c) then providing a readout subsequence which is spatially selective for NMR in the sample on the remaining surface and which occurs immediately prior to the commencement of acquisition of an NMR response signal from the desired voxel.
