Abstract
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.
