There is provided an MRI apparatus including a superconducting magnet that includes a refrigerant container and a superconducting coil, a cryogenic cooling system with which the superconducting magnet is provided, and a controller that controls the operation of the cryogenic cooling system. The cryogenic cooling system includes a cold head, a cryo-cooler, a compressor that supplies a compressed gas to the cryo-cooler, and a detection unit that detects the pressure in the refrigerant container, the refrigerant container being provided with the cold head, the cryo-cooler, the compressor, and the detection unit. An upper limit value of the maximum number of times of halts of the compressor within a predetermined period of time is set in advance. The controller intermittently halts the compressor within a range in which the pressure detected by the detection unit is equal to or lower than a predetermined upper limit value and performs control such that the number of times of halts of the compressor within the predetermined period of time reaches the upper limit value of the maximum number of times of halts.
