A magnetic resonance imaging apparatus includes a plurality of coils which receive magnetic resonance signals, a plurality of A/D converters which digitize the magnetic resonance signals, and a set unit which selectively sets a first state and a second state, the first state being set as a state in which the magnetic resonance signals output from the plurality of coils are input to the plurality of A/D converters, respectively, the second state being set as a state in which the magnetic resonance signal output from one of the plurality of coils is input to two or more of the plurality of A/D converters.
