ABSTRACT:
An MR imaging includes acquiring echoes from the object by implementing a pulse sequence which specifies the conditions which should be established with spins excited in the steady-state free precession (SSFP) method, so that the object can be scanned with an echo induced by water contained in the object and an echo induced by fat contained therein in single quadrature with each other or with a phase difference of 90° between the echoes induced by water and fat, constructing a tomographic image by performing frequency transformation on the acquired echoes, compensating the transformed data for the inhomogeneity in a static magnetic field and reconstructing an image, of which water and fat components are separated from each other, according to the result of the compensation.
