1. A magnetic resonance diagnosis apparatus performing “generation of image data of an object by magnetic resonance imaging”, and magnetic resonance spectroscopy, the magnetic resonance diagnosis apparatus comprising: an application region calculation unit configured to automatically calculate an application region of a spatially selective prepulse based on “image data including a region of interest of the object generated by magnetic resonance imaging before application of a prepulse”; and a data generation unit configured to receive a magnetic resonance signal from a data acquisition region including the region of interest after applying the prepulse according to the application region automatically calculated by the application region calculation unit, and generate magnetic resonance spectrum data indicative of concentration distribution per metabolic substance in the region of interest based on the magnetic resonance signal.
