Abstract
A magnetic resonance imaging apparatus according to an embodiment includes sequence controlling circuitry and processing circuitry. The sequence controlling circuitry performs a first acquisition and a second acquisition, the first acquisition including executing a preparation module corresponding to a first Echo Time (TE) value and subsequently performing an acquisition sequence, the second acquisition including executing the preparation module corresponding to a second TE value different from the first TE value and subsequently performing the acquisition sequence, the acquisition sequence being a pulse sequence including applying an RF excitation pulse in presence of a gradient magnetic field, and subsequently applying an RF re-focusing pulse in presence of another gradient magnetic field having an opposite polarity to that of the gradient magnetic field. The processing circuitry extracts at least one of a signal related to a first fat and a signal related to a second fat.
