According to one embodiment of the present invention, an MRI apparatus (20) includes a charge/discharge controlling unit (56, 126, 128), a judging unit (102, 132, 134, 136, 140 and 142) and a condition restricting unit (104). The charge/discharge controlling unit includes a charge/discharge element (126), receives electric power, and charges the charge/discharge element (126) by using the received electric power. The charge/discharge controlling unit also supplies a gradient magnetic field coil (26) with electric power discharged from the charge/discharge element (126) at a time of performance of magnetic resonance imaging. The judging unit judges whether capacitance of the charge/discharge element (126) falls below a threshold value or not. The condition restricting unit (104) restricts electric power amount supplied to the gradient magnetic field coil (26) by restricting conditions of an imaging sequence, when the capacitance of the charge/discharge element (126) falls below the threshold value.
