Two-dimensional (2D) MR spectroscopy enables feasible detection of low-concentration scalar-coupled metabolites in human tissues. However, the traditional acquisition of 2D MRS can be time consuming, and cross peaks which contain crucial spectral information in 2D correlated spectra (COSY) usually get contaminated by nearby strong diagonal peaks. Here, a pulse sequence is developed for ultrafast recording of diagonal-free 2D MR correlated spectra, thus allowing improved recognition and measurement of scalar-coupled metabolites.
