Data Reduction Analysis for Brain MR Elastography
Introduction Magnetic resonance elastography (MRE) is a method for quantitatively assessing the stiffness of tissue non-invasively by using phase contrast MRI to visualize and measure the propagation speed with which shear waves travel through the tissue of interest [1]. There is an increasing interest in applying the technology as a way to characterize the mechanical properties of the brain [2...
متن کاملMR elastography and MRI volumetry of the aging brain
Background: Physiological aging of the brain is accompanied by ubiquitous degeneration of neurons and oligodendrocytes [1]. An alteration of the cellular matrix of an organ impacts its macroscopic viscoelastic properties, which are characterized by mechanical parameters such as stiffness and internal friction. To date Magnetic Resonance Elastography (MRE) is the only non-invasive technique for ...
متن کاملMR Elastography for Studying the Biomechanics of Traumatic Brain Injury
P. J. McCracken, A. Manduca, R. L. Ehman Mayo Clinic and Foundation, Rochester, MN, United States Synopsis: The mechanisms by which head trauma causes hemorrhage, cerebral contusions and diffuse axonal injury are theorized as resulting from angular acceleration and its resulting shear motion. To develop a technique for studying the underlying biomechanics of brain trauma, we implemented a metho...

متن کاملMR Elastography Demonstrates Increased Brain Stiffness in Normal Pressure Hydrocephalus.
BACKGROUND AND PURPOSE Normal pressure hydrocephalus is a reversible neurologic disorder characterized by a triad of cognitive impairment, gait abnormality, and urinary incontinence that is commonly treated with ventriculoperitoneal shunt placement. However, multiple overlapping symptoms often make it difficult to differentiate normal pressure hydrocephalus from other types of dementia, and imp...
