Chemical shift artifacts occur in Spin-Echo MR images and are responsible for spatial misregistration. Numerous different techniques have been proposed but they always constrain the acquisition process. We present an image processing method to correct these artifacts. It is based on a pre-scan image of the fat and enables the correction of any Spin-Echo scheme sequence. Algorithm has been tested on several simulated images and on real images with good results.
