Abstract
A magnetic resonance imaging system includes a static field generating section, a gradient field applying section, high-frequency pulse applying section, a sequence control section, a receiving section and an imaging processing section. The sequence control section generates a 180.degree. pulse at a timing at which a center of the 180.degree. pulse appears at time t=TE'/2 when a center of a 90.degree. pulse appears at time t=0 under the condition TE'=TE-N.tau.c (where TE is an echo time with respect to a proton, .tau.c is a period in which phases of spins of the proton and fat match with each other and which is obtained on the basis of a chemical shift of protons of water and the fat, and n is an integer not less than 1), and generates a read gradient field Gr such that its intensity is set to allow an echo peak to appear at time t=TE=TE'+n.tau.c.
