Objective：To study the MSCT findings and clinical value of tendon in previous diabetic foot (Wegener 0 grade). Methods：MSCT data from 63 patients with previous diabetic foot and 33 cases of control group at our department from January 2011 to December 2013 were analyzed retrospectively. All patients were measured the thickness and CT value of the Achilles tendon and plantar aponeurosis, observed the tendon margin and recorded other imaging findings in foot. All patients with previous diabetic foot were further investigated the correlation of the thickness of tendon and the fasting blood glucose, the thickness of tendon and glycosylated hemoglobin, the CT value of tendon and the fasting blood glucose, the CT value of tendon and the glycosylated hemoglobin. Results：The thickness of Achilles tendon and plantar aponeurosis increased, compared to that in the control group (t=3.157, 4.462, P＜0.05). The density of Achilles tendon and plantar aponeurosis were lower than that of in the control group (t=2.176, 2.815, P＜0.05). The majority margin of the Achilles tendon and plantar aponeurosis were indistinct and the swelling foot tissues were showed in previous diabetic foot patients. While smooth-edges and normal foot tissues were demonstrated in the control group. Further correlation analysis showed a positive correlation between the thickness of tendon and glycosylated hemoglobin. The negative correlation was found between the density of tendon and glycosylated hemoglobin. Conclusion：MSCT could evaluate the tendon lesion in previous diabetic foot patients that is available to diagnose and treat the diabetic foot in early stage.
