Abstract:
1. A magnetic resonance imaging apparatus comprising: a chemical shift data storage unit configured to store chemical shift data of a plurality of substances which are to be targets for chemical shift imaging; a first frequency adjusting unit configured to adjust a center frequency of a first excitation pulse to a resonant frequency of a designated first substance; a first imaging unit configured to acquire a first magnetic resonant signal from a region containing the first substance by performing a first chemical shift imaging scanning with the first excitation pulse and generate an image in which the first substance is enhanced by using the first magnetic resonant signal; a second frequency adjust unit configured to automatically adjust a center frequency of a second excitation pulse to a resonant frequency of a preliminarily designated second substance in accordance with chemical shift data about at least one of the first substance and the second substance stored in the chemical shift data storage unit; and a second imaging unit configured to acquire a second magnetic resonant signal from a region containing the second substance by performing a second chemical shift imaging scanning with the second excitation pulse and generate an image in which the second substance is enhanced by using the second magnetic resonant signal.
