A magnetic resonance imaging apparatus is provided. The apparatus includes an imaging unit applying a gradient magnetic field and a radio frequency pulse to an inspection body in an magnetostatic field and generating a magnetic resonance signal, a bed having a top panel for placing the inspection body thereon and sliding the top panel in a longitudinal direction, a radio frequency coil for detecting the magnetic resonance signal, a display unit displaying a positioning image, a determining unit determining an ROI (a region of interest) on the basis of designation on the positioning image, a comparing unit comparing the ROI with an available FOV (a field of view) defined by the magnetostatic field, a calculating unit calculating a plurality of FOVs including the ROI when the comparing unit determines that the size of the ROI is greater than that of the available FOV, and a control unit controlling the imaging unit, the bed, and the radio frequency coil so as to perform an imaging operation on each of the FOVs.
