A 58-year-old male patient diabetic for 2 years controlled on oral anti-glycemic drugs, with no signs or symptoms of DPN with normal nerve conduction study. A The right PTN in relation to the PTA with its CSA measuring 18 mm2. B B-mode image shows the longitudinal axis of the right PTN. C The right image is the B-mode, the left image measures the elasticity of the PTN (40.9 kPa) with a color-coded box, circular ROI (T2) for quantitative measurements, and a color code scale at the top side of the image. D The left PTN in relation to the PTA with its CSA measuring 21 mm2. E B-mode image shows the longitudinal axis of the left PTN. F The right image is the B-mode, the left image measures the elasticity of the PTN (46.1 kPa) with a color-coded box, circular ROI (T3) for quantitative measurements, and a color code scale at the top side of the image. There is a mild increase in the CSA and nerve stiffness of both tibial nerves; however, the patient has no clinical or neuro-electrical signs of DPN denoting that SWE can estimate the state of the neuropathy even whenever ever it is still subclinical
