Method and system for multidimensional localization and for rapid magnetic resonance spectroscopic imaging

A method of prelocalizing magnetic resonance within a volume of interest comprising the steps of:

• applying a presuppression sequence to saturate volumes outside the volume of interest, said presuppression sequence including a spatial presuppression sequence;
• applying a series of three 90.degree. RF pulses to induce a stimulated echo within said volume of interest;
• applying a suppression sequence during an interval between second and third of said series of three 90.degree. RF pulses to saturate volumes outside the volume of interest, said suppression sequence including a spatial suppression sequence substantially identical to said spatial presuppression sequence, and wherein said presuppression sequence and said suppression sequence define the volume of interest in at least two spatial dimensions.

A magnetic resonance system for prelocalizing magnetic resonance within a volume of interest, said system comprising:

• means for applying a first suppression pulse sequence;
• and
• means for applying, after said first suppression pulse sequence, a stimulated echo pulse sequence to induce a stimulated echo in said volume of interest, wherein said stimulated echo pulse sequence includes a second suppression pulse sequence during a mixing time period of said stimulated echo pulse sequence, said first and second suppression pulse sequences each including a substantially identical spatial suppression pulse sequence to define said volume of interest.
