PROBLEM TO BE SOLVED: To provide a superconductive magnet device monitoring system, a superconductive magnet device monitoring method, and an MRI device capable of detecting the abnormality of a liquid helium state even in the case that the inside of a liquid helium vessel is occluded by solid air, and capable of performing maintenance on a suitably timely basis. SOLUTION: This superconductive magnet device monitoring system is equipped with a detective means 133, a remaining quantity prediction means 311 and an output means 420. The detective means 133 detects the remaining quantity of liquid helium stored in a liquid helium vessel 120 of a superconductive magnet device 110 that stores liquid helium in which superconductive coils are immersed. The remaining quantity prediction means 311 computes the predicted value of the remaining quantity based on the remaining quantity of the liquid helium tentatively detected by the detective means 133. The output means 420 outputs the monitoring information of the superconductive magnet device 110 based on the detected remaining quantity and the predicted value of the remaining quantity of the liquid helium.
