Shear Wave Elastography in Diagnosing Secondary Hyperparathyroidism [PDF]
Diagnostics, 2019 This study evaluates the diagnostic value of two-dimensional shear wave elastography (2 D-SWE) technique in the evaluation of hyperplastic parathyroid glands in cases with secondary and tertiary hyperparathyroidism. A total of 59 patients (end-stage renal disease, under supplemental dialysis program) with visible parathyroid hyperplastic glands on ...

Elastic waves in a soft electrically conducting solid in a strong magnetic field [PDF]
, 2017 Shear wave motion of a soft, electrically-conducting solid in the presence of a strong magnetic field excites eddy currents in the solid. These, in turn, give rise to Lorentz forces that resist the wave motion. We derive a mathematical model
