Renal Shear Wave Elastography for Differentiating Vasculitic and Non-Vasculitic Acute Kidney Injury.

However, renal cortical stiffness values in the non-vasculitic AKI group were numerically higher than those observed in healthy controls but did not reach statistical significance. This observation is consistent with prior insights, as highlighted by Barr and colleagues, emphasizing that shear wave elastography reflects a complex interplay of tissue inflammation, interstitial edema, and microvascular alterations rather than renal dysfunction alone [ 27 ].
