MR Elastography-Derived Shear Stiffness Could Be Biomarker for IVD Degeneration
ثبت نشده
چکیده
In a cross-sectional study, published in Radiology, in vivo lumbar MR elastography was performed once in the morning and once in the afternoon in 47 subjects without low back pain. Patients were ages 20 to 71 years. Researchers used principal frequency analysis to assess degeneration grade and MR elastography-derived sheer stiffness of the nucleus pulposus and annulus fibrous regions of all lumbar IVDs.

MR Elastography-derived Stiffness: A Biomarker for Intervertebral Disc Degeneration.
Purpose To determine the repeatability of magnetic resonance (MR) elastography-derived shear stiffness measurements of the intervertebral disc (IVD) taken throughout the day and their relationship with IVD degeneration and subject age. Materials and Methods In a cross-sectional study, in vivo lumbar MR elastography was performed once in the morning and once in the afternoon in 47 subjects witho...
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 کاملFeasibility of Detecting Spinal Instability in a Goat Spine Segment Using MR Elastography
Introduction: It has been reported that up to 85% of people will experience low-back pain (LBP) in their lives. Degenerative disc disease (DDD) and spinal instability are two of the most common causes of LBP. There are many imaging techniques that have been developed to characterize the disc and grade the level of degeneration, but there is no way to directly assess the material properties of t...
متن کاملMagnetic Resonance Elastography of the Heart
Cardiac magnetic resonance (MR) elastography noninvasively provides mechanics-based image contrast. The measurement of mechanical parameters is otherwise possible only by palpation or invasive pressure measurement. Measurement of parameters of myocardial shear stiffness is considered to be diagnostically beneficial especially in patients with diastolic dysfunction due to diffuse myocardial dise...
متن کاملMR elastography following focused ultrasound treatment of uterine fibroids
Background Magnetic Resonance Elastography (MRE) is a technique in which shear waves are induced in soft tissues and are imaged by Magnetic Resonance (MR) is to assess tissue stiffness. While gadolinium has served as the standard for assessing immediate post treatment changes in the fibroids, some patients may have allergies to gadolinium preventing use of this contrast agent. Additionally, som...
