Abstract Objective: To evaluate the value of two-dimensional high-frequency ultrasonography and power Doppler imaging(PDI) for judgement of the abnormalities of Achilles tendon in patients with type 2 diabetes mellitus(T2DM). Methods: A total of 60 patients of T2DM were enrolled and divided into two groups: group B(30 cases, the course≤10 years), group C(30 cases, the course>10 years). Thirty healthy subjects were enrolled in group A as normal control. The echotexture of Achilles tendon and blood flow were observed by two-dimensional high-frequency ultrasonography and PDI. The thickness(D1) and width(D2) of each tendon were measured at its starting point, middle point and insertion. Results: The ultrasound imaging of Achilles tendons in group A was shown string like homogeneous hyperechogenicity with clear border with surrounding tissue. The abnormal ultrasound findings, such as hypoechoic areas, heterogenous echogenicity, or indistinct border with surrounding tissue, were more frequently detected in group B and C than group A(all P<0.05). The ratio of calcification of group C was larger than that of group A(P<0.05). There were no significant difference in the ratios of abnormalities of the surrounding tissue among the groups of A, B and C(all P>0.05). At starting point, the thicknesses(D1) of group C were larger than group A(all P<0.05). At middle point, the thicknesses(D1) of group B and group C were larger than group A(all P<0.05), and the thicknesses(D1) of group C were larger than group B(all P<0.05). In the insertion, the thicknesses(D1) of group B and group C were larger than group A(all P<0.05). The blood flow of grade 1 was the most normal sign in the Achilles tendons in the groups of A, B and C. There were no significant difference among the groups of A, B and C in gradings of blood flow. Conclusions: To evaluate the abnormal echotextures, thickening and blood flow of Achilles tendons in the patients of T2DM by Two-dimensional high-frequency ultrasound and PDI are valuable for clinical.
