Abstract

A magnetic resonance imaging (MRI) system and method integrating multi-nuclide synchronous imaging and spectral imaging is provided. The MRI system includes a spectral imaging module, a multi-nuclide synchronous imaging module, and a spectral reconstruction and image fusion module, where the spectral imaging module is configured to acquire a spectrum of a nuclide Nuc; the multi-nuclide synchronous imaging module is configured to perform synchronous imaging of nuclides Nuc1 . . . Nucn, where when n=1, Nucl is 1H; and when n>1, Nucn is a non-1H nuclide; and the spectral reconstruction and image fusion module is configured to receive the spectrum of the nuclide Nuc and images of the nuclides Nuc1 . . . Nucn, and acquire spatial distribution information of compounds of the nuclide Nuc and spatial distribution information of the non-1H nuclide through fusion. The system and method can synchronously acquire MR signals of different nuclides, and reconstruct and fuse non-1H nuclide images.
