1. A magnetic resonance imaging apparatus comprising:
sequence control circuitry that repeatedly performs a first data acquisition for acquiring first data relating to a measurement target, using a first MRS pulse sequence including a first frequency selection means based on a first frequency selection pattern that includes a plurality of frequency selective pulses, and a second data acquisition for acquiring second data relating to the measurement target, using a second MRS pulse sequence including a second frequency selection means for selecting a second frequency selection pattern that differs from the first frequency selection pattern and includes a plurality of frequency selective pulses, wherein
the plurality of frequency selective pulses make selection frequencies of frequency selective pulses before and after an excitation pulse differ and/or are optimized so as to make (tTE−tJ) differ from tJ wherein tJ is a time between the plurality of frequency selective pulses and tTE is an echo time.
