This application describes a new method for proton magnetic resonance spectroscopic imaging. This new method does not have the limiting disadvantages of the previous techniques. The method combines multi-slice and multi-spin-echo techniques for high signal-to-noise ratio per unit time and high efficiency spectroscopic information. This invention can also produce compound weighted spectroscopic images by selecting the period between refocussing pulses according to the coupling constant of a group contained in the compound. Application of a pulse sequence to conventional MRI imaging apparatus allows for rapid acquisition of data for generating spectroscopic images.
