According to one embodiment, the MRI apparatus includes an RF coil apparatus having a coil element, a coil port to which the RF coil apparatus is connectible, receive circuitry receiving a signal detected by the RF coil apparatus via the coil port when neither an RF pulse nor a gradient magnetic field is being applied, and performing A/D conversion with an A/D converter, and processing circuitry detecting an abnormality based on the signal. With the RF coil apparatus being connected to the coil port, the receive circuitry switches at least one switch provided in a section between the coil element and the A/D converter between on and off, and receives the signal. The processing circuitry compares a signal of a path where the coil element and A/D converter are connected with a signal of a path where the coil element and A/D converter are not connected, and detects the abnormality.

Magnetic resonance imaging apparatus and abnormality detection method

A magnetic resonance imaging apparatus according to an embodiment includes processing circuitry and a display. The processing circuitry acquires information of an RF (radio frequency) coil. The processing circuitry sets a protocol to be applied to imaging using the RF coil before execution of the imaging. When there are a plurality of protocols that can be selected as the protocol applied to the imaging, the display displays at least one protocol narrowed down from the protocols as the protocol that can be applied to the imaging, based on information of the RF coil.
