Inspection method and inspection apparatus using nuclear magnetic resonance

In an inspection method which generates a static magnetic field, a gradient magnetic field and a radio frequency magnetic field, detects nuclear magnetic resonance signals from an inspection object, computes and processes the nuclear magnetic resonance signals so detected and outputs the result of computation processing, a gradient magnetic field for generating signal attenuation by diffusion and an oscillating gradient magnetic field for generating chemical shift information and spatial information of the materials contained in the inspection object are applied, separation and acquisition of spatial information of each material contained in the inspection object are simultaneously conducted, and a measurement time is shortened.
