Ultrasound shear wave elastography and multifrequency magnetic resonance elastography for detection of chronic renal allograft dysfunction

Purpose: Kidney transplant dysfunction is associated with viscoelastic tissue changes. The purpose of this study is to noninvasively assess renal stiffness in kidney transplant recipients using ultrasound shear wave elastography (SWE) and to correlate shear wave velocity (SWV) with renal allograft function and shear modulus values obtained by magnetic resonance elastography (MRE). Materials and methods: This prospective study investigated 25 transplant kidneys (functional renal allograft, fct, n = 14; renal allograft insufficiency, dys, n = 11) in 20 kidney transplant recipients (mean age, 43 ± 14 years).
