Abstract:
Objective To investigate the clinical values of quantitative ultrasound elastography technique in detecting internal carotid artery thickness .Methods One hundred and forty healthy objects who have conducted physical examination in our hospital from February 2012 to August 2015 were selected ,and divided in to three groups:the healthy control group (n=40;IMT<0 .9 mm) ,the IMT thickening group (n=60;0 .9 mm≤ IMT < 1 .3 mm) and plaque group(n= 40 ;IMT ≥1 .3 mm) .All the three groups conducted routine ultrasound and quantitative ultrasound elastography ,and the clinical data investigation and laboratory ex‐amination were carried out at the same time .Results The TC ,LDL‐C values in the plaque group and intimal thickening group were significantly higher than the control group (P<0 .05) .The AC values in the plaque group and intimal thickening group were signif‐icantly higher than the control group (P<0 .05) ,while the AI and PWVβvalues were significantly lower(P<0 .05) .Linear corre‐lation analysis showed that IMT were positively correlated to the AI ,PWVβ (r=0 .512 ,P <0 .05 ;r= 0 .483 ,P<0 .05) ,and the AC were negatively correlated (r= -0 .713 ,P<0 .05);Logistic analysis showed that LDL‐C ,AC ,PWVβwere the major independ‐ent risk factors for IM T (P<0 .05) .Conclusion Ultrasound elasticity quantitative detection of neck vessels is safe and can non‐in‐vasive dynamically observe blood vessel wall changes during the progression of atherosclerosis ,thus it's helpful in the judge and i‐dentification of internal carotid artery thickness .
