Claim:
1. A magnetic resonance (MR) imaging apparatus comprising: MRI system components including static and gradient magnetic field generators, at least one radio frequency (RF) coil, an RF transmitter, an RF receiver and at least one computer configured to control said components to acquire frequency spectra including a first frequency spectrum of first MR signals and a second frequency spectrum of second MR signals from an object, said spectra exhibiting a changing suppression effect or a changing enhancing effect of signals from a specific material; obtain a resonance frequency of the specific material or another material using a frequency spectrum, for obtaining the resonance frequency of the specific material or the another material, selected from the first frequency spectrum and the second frequency spectrum based on an index representing a difference in intensities of signals from the specific material or the another material between the first frequency spectrum and the second frequency spectrum; and perform MR imaging using a radio frequency pulse having a center frequency set to the resonance frequency of the specific material or the another material.
