ABSTRACT:
In a magnetic resonance imaging system for acquiring a magnetic resonance signal from a three-dimensional region to be imaged by executing a data acquisition pulse sequence based on a three-dimensional Fourier transform method including selective excitation, regions located on both sides of the three-dimensional region in a slice direction are presaturated prior to execution of the data acquisition pulse sequence based on the three-dimensional Fourier transform method including selective excitation, a region which includes the three-dimensional region and is broader than the three-dimensional region in the slice direction is then selectively excited, and the data acquisition pulse sequence based on the three-dimensional Fourier transform method is executed, thereby acquiring a magnetic resonance signal from the three-dimensional region.
