Ultrasound Strain and Strain Rate Imaging of Carotid Artery with the Early Sage of Type 2 Diabetes Mellitus

Abstract

The objective of this paper is to evaluate the value of ultrasound strain and strain rate imaging in evaluating the motorial characteristics of the early stage of the CCA in patients with type 2 diabetes mellitus (DM2). Fifty patients without vascular complications with type 2 diabetes and fifty healthy volunteers underwent carotid ultrasound are selected as objects in the examinations and the dynamic image was analyzed by the off-line software (syngo Velocity Vector Imaging technology [VVI], Siemens). The results show that Vmax of anterior wall, anterolateral wall and posterolateral wall were higher than those of posterior wall, posteromedial wall, and anteromedial wall (P<0.05). VTTP, Vmax, Smax, and SRmax of corresponding segments had significant differences in study group and control group (P<0.05). From the results, it could be concluded that Velocity Vector Imaging can be used to evaluate the change of common carotid elasticity in early stage of AS in patients with type 2 diabetes.
