Abstract: A magnetic resonance imaging (MRI) apparatus includes a coil assembly including a superconductive magnet; and a helium container configured to accommodate a helium in a liquid state and the coil assembly. The helium container includes a partition wall configured to surround a portion of an outer circumference of the coil assembly, and the helium in the liquid state is accommodated in a first space formed between the partition wall and the coil assembly.
