A medical information processing apparatus according to an embodiment includes determination circuitry and display control circuitry. The determination circuitry determines whether there is a change in an amount of individual metabolites among a plurality of metabolites in magnetic resonance spectroscopy within a part worthy of attention set on medical image data by comparing the amount of each of the plurality of metabolites with a reference value corresponding to each metabolite. The display control circuitry display identification information by associating therewith the part worthy of attention, the identification information identifying whether the amount of each of the plurality of metabolites is changed.
