Figure 5 Quantitative elastography measurement at the interpolar region of a transplant kidney with acute allograft dysfunction due to acute tubular necrosis. A: Gray scale image; B: Color-coded map elasticity values distribution on a scale of 0 to 80 kPa and corresponding gray scale image (mean value 350 kPa and 3.4 m/s); C: Histopathological section shows acute tubular injury with dilation of tubules (blue arrow) and flattening of tubular epithelial cells (orange arrow; × 100 original magnification, H&E stain, scale bar = 100 μm).
