The present invention aims to receive a signal of tissue long in T2 at a relatively high level and suppress artifacts. When a magnetic resonance frequency of a component intended for measurement is assumed to be Omega and the frequency corresponding to a repetition time TR is assumed to be omegao, an RF pulse obtained by modulating a chemical shift SAT pulse for reducing a signal of a frequency Omega with cos (omegao.t) is applied as a leading pulse Po and thereafter a pulse sequence of Balanced SSFP is applied. Since a signal leading to the occurrence of artifacts is reduced owing to the effect of the leading pulse, the artifacts can be suppressed. Since a transient state is long in the same manner as conventional, such a signal of tissue long in T2 can be received at the relatively high level and contrast can be kept high by executing data acquisition in the transient state.
