Figure 7 Quantitative elastography measurement at the interpolar region of a transplant kidney with acute allograft dysfunction due to calcineurin inhibitor toxicity. A: Gray scale image; B: Color-coded map of elasticity value distribution on a scale of 0 to 80 kPa and corresponding gray scale image (mean value 331 kPa and 3.3 m/s); C: Histopathological section shows features of CNI toxicity in form of beaded nodular adventitial fibrosis (green arrow) from a case of renal allograft recipient (× 400 original magnification, PAS stain, scale bar = 200 μm).
