Claim One:
1. A method for generating a magnetic resonance elastography (MRE) image: a) positioning a subject within the MRI system; b) coupling a driver to the subject to impart oscillating energy to the subject; c) using the MRI system and in coordination with operation of the driver, performing a pulse sequence having positive and negative motion encoded gradients to acquire positively motion encoded medical imaging data and negatively motion encoded medical imaging data from the subject; d) transforming the positively motion encoded medical imaging data and negatively motion encoded medical imaging data for a given slice into a positively encoded medical image and a negatively encoded medical image of the subject; e) deriving a difference image from the positively encoded medical image and the negatively encoded medical image; f) transforming the difference image into difference medical imaging data; g) applying a filter to correct for errors in the difference medical imaging data associated with phase ramps during the pulse sequence and create filtered medical imaging data; h) deriving a filtered difference image from the filtered medical imaging data; i) generating a corrected difference image from the filtered difference image and the difference image; j) repeating steps d) through i) for each slice acquired in step c); and k) generating a report of elastic properties of the subject from the corrected difference image.
