Synopsis

Keywords: Other Musculoskeletal, Elastography

Motivation: The purpose of study was integration of Dixon and X-ray CT like image technique in the GRE-MultiEcho-MRE sequence.

Goal(s): The additional visualization of bone damage and water / fat compornents on MR elastography would yield benefits in evaluating radiologic skeletal muscle evaluation, since soft tissue injuries can be assessed directly related to the osseous injuries using one image modality.

Approach: The effectiveness of this method was evaluated by volunteer studies using the original MRE pulse sequence and vibration system.

Results: This method allows simultaneous acquisition of elastograms, wave images, water/fat component images and X-ray CT like images.

Impact: For the patient, a reduction in total imaging time is beneficial. For the clinicians, images such as elastograms, wave images, water/fat component images, and X-ray CT are available simultaneously for multimodal diagnosis.
