To properly set the condition of scan for calibration such as pre-scan without taking time and labor of a user for a setting operation, in an MRI.

In one embodiment, an MRI apparatus (20) includes a main scan executing unit for executing a main scan, an image reconstruction unit (90) for reconstructing image data based on magnetic resonance signals collected in the main scan, a calibration scan setting unit (100), a calibration scan executing unit, and a condition determining unit. The calibration scan setting unit (100) calculates and automatically sets the condition of a calibration scan used for determining the imaging condition of the main scan or a condition of reconstruction processing according to the type of an RF coil device and an imaging part. The calibration scan executing unit executes the calibration scan based on the automatically set condition of the calibration scan. The condition determining unit determines the imaging condition of the main scan or the condition of the reconstruction processing based on an execution result of the calibration scan.
