Abstract
A magnetic resonance diagnosis apparatus automatically calculates an application region of a prepulse based on image data including a region of interest of an object generated before application of a prepulse. The prepulse is applied to the automatically calculated application region. A magnetic resonance signal is then received from a region including the region of interest, and magnetic resonance spectrum data is generated indicative of concentration distribution of metabolic substances in the region of interest.
