PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging apparatus having a high speed and high sensitivity and capable of acquiring magnetic resonance spectra from a plurality of regions.
SOLUTION: The apparatus comprises a receiver probe, a sequence control means, and an operation means. The receiver probe is made by arranging a plurality of small-sized coils, whose ratio of the length in the short axis direction to that in the long axis direction is one to two or more, in the short axis direction. The sequence control means controls generation of a high frequency magnetic field, generation of gradient magnetic fields which give positional information of the small-sized coil in the long axis direction, and detection of a plurality of magnetic resonance signals by the plurality of small-sized coils. The operation means calculates, using the plurality of magnetic resonance signals, spectrum information containing spatial information of the small-sized coils in the short axis direction that corresponds to the sensitivity region of each small-sized coil and positional information of the small-sized coil in the long axis direction given by the gradient magnetic fields.
