A magnetic resonance imaging apparatus according to an embodiment is a magnetic resonance imaging apparatus including a gradient coil unit configured to generate a gradient magnetic field in an imaging space in which a subject is placed. The gradient coil unit includes a cooling layer configured to cool the gradient coil. The cooling layer includes a first cooling pipe configured to cool the gradient coil entirely and a second cooling pipe configured to locally cool the gradient coil.

Magnetic resonance imaging apparatus

A magnetic resonance diagnostic apparatus is configured in such a manner that: a high-frequency transmission coil transmits a high-frequency electromagnetic wave at a magnetic resonance frequency to an examined subject; a heating coil performs a heating process by radiating a high-frequency electromagnetic wave onto the examined subject at a frequency different from the magnetic resonance frequency; based on a magnetic resonance signal, a measuring unit measures the temperature of the examined subject changing due to the high-frequency electromagnetic wave radiated by the heating coil; and a control unit exercises control so that the measuring unit measures the temperature while the heating coil is performing the heating process, by ensuring that the transmission of the high-frequency electromagnetic wave by the high-frequency transmission coil and the radiation of the high-frequency electromagnetic wave by the heating coil are performed in parallel.
