Abstract
A system for magnetic resonance imaging is provided in which a prepulse is first applied to an object being examined placed in a static magnetic field for suppressing an MR signal from fat of the object. Then a pulse sequence including an RF pulse for multi-slice imaging of a plurality of slicing planes is applied to the object for acquiring image data. The system comprises an element for performing a shimming increasing uniformity of the static magnetic field, an element for detecting, every one of the slicing planes, an offset value offsetting a frequency shift of a spectrum distribution caused by turbulence in higher-order components of the static magnetic field, and an element for correcting, every one of the slicing planes, a frequency range of the prepulse in accordance with the offset value detected. The correcting element corrects a frequency of the RF pulse in compliance with the detected offset value.
