FIGURE 2
Figure 2: short-axis view main patterns of VN changes detected in diabetic patients; the CSA of the vagus nerve was significantly smaller in patients compared with controls with different aspects:
a - smaller but with well preserved internal fascicular structure;
b - smaller and hypoechoic, with some appreciable internal structure;
c - small size, hyperechoic with thin hyperechoic rim;
d - small size, hypoechoic with the hyperechoic rim.
