A magnetic resonance imaging (MRI) system and method uses an MRI gantry having a static magnet structure, controllable gradient magnet structures and at least one radio frequency (RF) coil for transmitting and receiving RF signals to and from an imaging volume. Control circuits are configured to control gradient magnetic fields generated by the gradient magnet structures, to transmit/receive RF signals to and from the at least one RF coil and to process RF signals received during a diagnostic MRI scan to produce displayable images of structures located within the imaging volume. The control circuits are configured to include a preparatory fat decoupling RF pulse as part of a patient ROI (region of interest) shimming sequence effected prior to a fat suppression type of diagnostic MRI data acquisition scan sequence. |
