Abstract
An MRI apparatus and a two-dimensional excitation adjustment method capable of performing appropriately two-dimensional excitation of a region, in which materials with different resonance frequencies are present, according to imaging conditions are provided. In order to do so, when performing the two-dimensional excitation of a two-dimensional excitation region of an object formed by a first material with a first resonance frequency and a second material with a second resonance frequency, an irradiation frequency of a high-frequency magnetic field for the two-dimensional excitation is set on the basis of the imaging conditions related to the two-dimensional excitation and the first and second resonance frequencies so that desired regions of the first and second materials are excited in a two-dimensional manner.
