According to one embodiment, an MRI apparatus (20A or 20B) includes a first radio communication unit (200A or 200B), a second radio communication unit (300A or 300B) and an image reconstruction unit (56). The first radio communication unit includes a connecting unit (201) detachably connected to an RF coil device (100A, 100B or 100C) which detects a nuclear magnetic resonance signal emitted from an object. The first radio communication unit acquires the nuclear magnetic resonance signal detected by the RF coil device via the connecting unit, and wirelessly transmits the acquired nuclear magnetic resonance signal. The second radio communication unit receives the nuclear magnetic resonance signal wirelessly transmitted from the first radio communication unit. The image reconstruction unit acquires the nuclear magnetic resonance signal received by the second radio communication unit, and reconstructs image data of the object based on the nuclear magnetic resonance signal.
