A magnetic resonance diagnosis apparatus includes a coil assembly including a high-frequency coil, a transmission unit which excites magnetization of a specific atomic nucleus of an object via the high-frequency coil, a reception unit including a detection unit for receiving a magnetic resonance signal via the high-frequency coil, a low-pass filter, and an analog/digital converter, a control unit which sets a passband of the low-pass filter to not less than three odd multiple of a frequency band determined from an imaging field of view, and sets a sampling frequency of the analog/digital converter to an oversampling frequency exceeding a signal band of the magnetic resonance signal, a noise spatial distribution generating unit which generates a noise spatial distribution on the basis of an output from the reception unit.
