Abstract
According to one embodiment, a magnetic resonance imaging apparatus includes processing circuitry. The processing circuitry is configured to design a pulse sequence including a plurality of refocus pulses and a plurality of crusher gradient fields, in such a manner that a first crusher gradient field to be applied after a first refocus pulse group and a second crusher gradient field to be applied before a second refocus pulse group after the first refocus pulse group overlap one another at least partially. The processing circuitry is configured to acquire magnetic resonance spectroscopic signals by executing the designed pulse sequence.
