Abstract:
Objective To investigate the application value of the ultrasonic elastic tissue dispersion quantitative analysis technique in different stages of subacute thyroiditis (SAT).Methods One hundred and forty-four SAT lesions detected from 81 patients were enrolled in the patient group.They were further divided into three subgroups,including acute group (group Ⅰ),medium group (group Ⅱ) and recovery group (group Ⅲ).Another 59 healthy volunteers were collected as control group.All the participants accepted conventional ultrasound and elastographic examinations.Eleven parameters were obtained by the tissue dispersion quantitative analysis software.These parameters were compared between groups and among subgroups by ANOVA.The correlation between all the parameters and the course of SAT were analyzed by Spearman and Multiple linear regression methods.Results Between groups and among subgroups,the complexity (COMP) and correlation (CORR) were not statistically different(all P ＞0.05).Differences of kurtosis (KURT) and angular secon moment (ASM) among the three subgroups were not significant (all P ＞0.05).Differences between groups and among subgroups were significantly different among the value of all the other seven indexes (all P ＜0.01).Moreover,they were all correlated with the clinical staging,with the highest coefficient in area ration of low-strain region (％ AREA)(r =-0.881).Regression model was constructed and only ％ AREA was selected into the regression equation.ROC curves were constructed to estimate the clinic value of ％ AREA in staging patients of SAT,the areas under ROC curves were0.986(group Ⅰ vs group Ⅱ-Ⅲ) and 0.988 (group Ⅰ-Ⅱ vs group Ⅲ[) for ％AREA,respectively.Conclusions The tissue dispersion quantitative analysis technique is helpful in estimating the stiffness of thyroid in patients with SAT.
