MR Elastography

Magnetic resonance elastography (MRE) is a relatively new technique that images and measures the mechanical properties of the tissues. MRE provides noninvasive quantitative parameters that are useful in the evaluation of various disease processes of the organs. Currently, MRE is widely used for the assessment of liver fibrosis. MRE of the brain is emerging as a valuable clinical tool in the assessment of diffuse brain disease and preoperative evaluation of intracranial masses. Improvements in the MRE technology and recognition of increased stiffness as a parameter for the disease have set the stage for its application in the pancreas, spleen, prostate, kidneys, cardiac muscle, uterus, and skeletal muscles. Recent advances have also provided newer mechanical parameters that may help in differentiating disease processes that increase tissue stiffness.
