Patent ID: 7042215

Claim:
A method of chemical species suppression for MRI imaging of a scanned object region comprising: acquiring K space data using a spiral acquisition technique with a first TE of 2.2 milliseconds, a second TE of 4.4 milliseconds, and a third TE of 6.6 milliseconds, for purposes of performing three-point Dixon processing, wherein each TB is a multiple of 2.2 milliseconds; reconstructing three sets of image data having off resonance effects; estimating the off resonance effects at locations throughout the three reconstructed sets of image data; decomposing said three sets of reconstructed image data into water and fat image data sets each representing a separate chemical species; and correcting said water and fat image data sets for blurring resulting from off resonance effects due to local Bo inhomogeneity using said estimated off resonance effects, wherein each of the fat and water image data sets suppresses signals from other chemical species.
