Prediction of acute rejection in renal allografts using shear-wave dispersion slope

ConclusionShear-wave dispersion slope obtained at SWE may help identify renal allograft dysfunction.Clinical relevance statementAcute rejection in renal allografts is a major cause of allograft failure, but noninvasive diagnosis is a challenge. Shear-wave dispersion slope can identify acute rejection non-invasively.Key Points•The interstitial fibrosis and tubular atrophy grade was a determinant factor for stiffness ratio and shear-wave dispersion slope ratio between cortex and renal sinus fat.•Shear-wave dispersion slope ratio between cortex and renal sinus fat could identify acute rejection in renal allografts.•A shear-wave dispersion slope has a potential to reduce unnecessary renal biopsy for evaluating renal allografts.
