Comparison of resistive index and shear-wave elastography in the evaluation of chronic kidney allograft dysfunction

Figure 2 Histopathology results from allograft biopsies. A: In this case, there is early deposition of blue collagen in between the tubules, which are showing only mild atrophy. One glomerulus included is intact (Trichrome stain, × 200); B: In this example, there is moderate amount of fibrous tissue in the graft parenchyma and moderate tubular atrophy. One glomerulus included is intact (Trichrome stain, × 200); C: In this case, there is severe tubular atrophy associated with severe interstitial fibrosis. The included glomerulus is globally sclerosed (Trichrome stain, × 200).
