Chemical-Shift Selective Multislice Imaging Using the Gradient Reversal Technique

The chemical shift phenomenon can produce severe artifacts of geometric shift or blurring in MRI. Instead of treating the chemical shift phenomenon as a source of artifact, many imaging technologies, including the gradient reversal (GR) technique, have been developed to acquire separate sets of images from tissues of different resonance frequencies. Although the GR method has not been widely used, recent reports have confirmed the effectiveness of this method for fat suppression at 3.0T and higher field. In this abstract, we expand the concept of the GR technique to acquire multislice chemical-shift selective images.
