Patent ID: 8587305

Claim:
An MRI apparatus comprising: a magnetic resonance imaging (MRI) system having a plurality of gradient coils positioned about a bore of a magnet, and an RF transceiver system and an RF switch controlled by a pulse module to transmit RF signals to an RF coil assembly to acquire MR images of an object composed of at least a first species and a second species; and a computer programmed to: cause the MRI system to apply a pulse sequence; acquire a plurality of MR image data sets including a first species signal and a second species signal; generate a first species image from the acquired MR image data; generate a second species image from the acquired MR image data; identify voxels in the second species image representative of only the second species; for voxels identified as being representative of only the second species, calculate a fraction of the second species signal appearing in the first species image; and generate a modified first species image based on the fraction of the second species signal appearing in the first species image, the modified first species image having a different fraction of the second species as compared to the first species image.
