Abstract: Objective To evaluate the morphological changes of sural nerve in patients with type 2 diabetes mellitus by hyperfrequency ultrasound.Methods Fifty-six sural nerves of symptomatic group,64 sural nerves of asymptomatic group,and 60 sural nerves of control group were identified by 22 MHz Ultrasound.The thickness/width (T/W) ratio,cross-sectional areas (CSA) and the maximum thickness of neuronal fascicles (MT) of the sural nerve were calculated in transverse sonograms.Results ①Ultrasound can clearly show these structures of sural nerve such as epineurium,perineurium and nerve bundles and so on.②In symptomatic group,asymptomatic group and control group,T/W ratio and MT were gradually increased,and the differences among the three groups were statistically significant (P＜0.05).Whereas,there were no statistically significant differences in CSA among the three groups (P=0.257).Conclusions22 MHz ultrasound may be a valuable tool in evaluating the diabetic cutaneous nerve neuropathy
