Abstract
A magnetic resonance (MR) sequence (14) is performed, including: applying a preparatory MR sub-sequence (S prep) providing water signal suppression; performing a magnetic resonance spectroscopy (MRS) sub-sequence (S MRS) after applying the preparatory MR sub-sequence to acquire H MRS data with water signal suppression; and performing an MR reference sub-sequence (S Ref) to acquire MR reference data. The MR reference sub-sequence is performed after the MRS sub-sequence. Phase and B0 correction of the H MRS data with water signal suppression are performed using the MR reference data to generate corrected MRS data. The excitation pulse (g) of the MR reference sub-sequence has a flip angle of less than or equal to o, and more preferably has a flip angle of less than or equal to 3 o. In some embodiments the MR sequence has a total repetition time (TR) of 2000 msec or less.
