Recently, a relaxation-enhanced (RE) selective-excitation MRS approach to acquire in vivo localized spectra with flat baselines and very good signal-to-noise ratios (SNR) has been proposed. As RE MRS targets a priori known resonances, MRSI information may be acquired in a faster, more efficient manner. Hereby we present such Relaxation-Enhanced Chemical-shift-Encoded Spectroscopically-Separated (RECESS) MRI method, targeting images of various metabolite by collecting a series of conventional imaging data echoes where the chemical shifts of the different resonances are encoded by coherent phase modulations, and disentangled by Fourier-based inversions. The RECESS method thus accelerates the acquisition of quality MRSI data.
