## Abstract A method for the acquisition of localized 2D shift‐correlated spectra, based on the combination of the stimulated‐echo volume‐selection and gradient‐enhanced COSY experiments, is described. The sequence can be modified to perform a number of localized experiments including HOHAHA and DQ

✦ Synopsis
The purpose of this study was to acquire a localized 2D (two-dimensional) 1 H correlation spectrum, in a volume of interest reasonably small, and within an experiment time compatible with clinical applications. A modified PRESS technique has been used. The last 180°pulse of the PRESS sequence has been converted into a 90°pulse for both refocusing and coherence transfer. 2D correlation spectroscopy was performed on healthy volunteers in a clinical magnet, at 3 T, within 34 min, for a voxel size of 27 cm 3 . This result makes it possible to consider clinical applications.
