FIELD: physics.
SUBSTANCE: invention can be used to analyse an object using a magnetic resonance technique. A magnetic resonance (MR) sequence is performed, which includes applying a preparatory MR sub-sequence (Sprep) providing water signal suppression; performing a magnetic resonance spectroscopy (MRS) sub-sequence (SMRS) after applying the preparatory MR sub-sequence to acquire 1H MRS data with water signal suppression; and performing an MR reference sub-sequence (SRef) to acquire MR reference data. The MR reference sub-sequence is performed after the MRS sub-sequence. Phase and B0 correction of the 1H MRS data with water signal suppression are performed using the MR reference data to generate corrected MRS data. The excitation pulse (γ) of the MR reference sub-sequence has a flip angle of less than or equal to 5°, and more preferably has a flip angle of less than or equal to 3°. In some embodiments the MR sequence has a total repetition time (TR) of 2000 ms or less.
EFFECT: faster obtaining of measurement results with high accuracy.
