A sound wave is introduced through the tissue (usually generated from an ultrasound device), and the waveâ€™s propagation is measured using standard magnetic resonance imaging (mri).

Abstract many disease processes, both focal and diffuse, cause marked changes in cell and tissue mechanical properties. Magnetic resonance elastography (mre) is a magnetic resonance imaging-based technique for quantitatively assessing the mechanical properties of tissues based on the propagation of shear waves. Multiple studies have demonstrated mre can be successfully implemented to assess abdominal organs with many potential applications, from detecting diffuse disease processes to characterizing tumors. The first clinical application of mre to be well documented is the detection and characterization of hepatic fibrosis, which systematically increases the stiffness of liver tissue. cheap viagra online viagra for sale generic viagra online buy generic viagra buy cheap viagra cheap generic viagra cheap viagra viagra without a doctor prescription viagra without a doctor prescription viagra online In this diagnostic role, it offers a safer, less expensive, and potentially more accurate alternative to invasive liver biopsy. Emerging results also suggest that measurements of liver and spleen stiffness may provide an indirect way to assess portal hypertension. Preliminary studies have demonstrated that it is possible to use mre to evaluate the mechanical properties of other abdomin.
