<P>PROBLEM TO BE SOLVED: To more effectively suppress spatial magnetic resonance signals. <P>SOLUTION: A photography excitation pulse RF1 and a refocus pulse RF2 are successively applied; the first excitation pulse MEGA_RF1 and first gradient magnetic field SS_mega1 for exciting an atomic core spin at a specific part of a subject, and a first crusher gradient magnetic field Crusher_mega1 of a gradient axis direction PE following the first gradient magnetic field SS_mega1 for dispersing a phase of the excited atomic core spin are applied after application of the pulse RF1 and before application of the pulse RF2; a second excitation pulse MEGA_RF2 and a second gradient magnetic field SS_mega2 for exciting the atomic core spin at the specific part after application of the pulse RF2, and a spin echo system sequence for applying a second Crusher gradient magnetic field Crusher_mega2 following the second gradient magnetic field SS_mega2 are performed after application of the pulse RF2. On the basis of an obtained magnetic resonance signal, an image where a magnetic resonance signal from the specific part is suppressed is generated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
